Abstract— The technology of wind turbines as electric power

plants has developed very rapidly because renewable energy is

environmentally friendly and has unlimited availability. The use

of wind energy conversion systems for the grid non-connected

areas has greatly benefits for the community, in which small scale

standalone wind turbine systems are well suited to rural areas

due to low investment costs and are easily controlled to improve

efficiency. However, wind speed highly interfere the output

power of the wind turbine. The efficiency of wind turbine can be

improved by extracting the maximum power point to get optimal

power. In this paper will propose an optimal power extraction

control for small scale stand alone wind turbine using permanent

magnet synchronous generator (PMSG) based on fuzzy logic

controller (FLC) without mechanical sensors. Fuzzy logic

determines the optimum power point through the duty cycle

controlling on the dc/dc converter based on the uncontrolled

rectifier output voltage and current. Based on the simulation

results, FLC has better performance, where FLC can capture

greater output power than perturb & observe (P&O) method. At

wind speeds of 10 m/s, the use of FLC can extract wind power of

4200W while the P&O method is 3700W. In addition, FLC can

extract optimum power to wind speeds variation and generate no

oscillations.

I. INTRODUCTION

Until 2014, the growth of electrical energy needs experienced an average growth of 6.8% per year with electrification ratio of 84.4%. About 90% of national power plants use fossil fuels. Currently, the availability of fossil energy is dwindling and environmental pollution of CO2 gas emissions due to the use of fossil fuels is increasing. So it takes diversification of energy to develop renewable energy as a substitute for fossil energy. Wind energy is one of renewable energy that is growing very rapidly as a electricity generation. Indonesia's wind energy potential is estimated at 9,290 MW and newly utilized around 1.1MW [1].

Based on the electrification ratio, there are still some areas that have not been reached by the grid. Beside, Indonesia, as an archipelago, are still many small islands that have not been

reached by the grid. Stand alone small wind turbine systems with batteries, as energy stores, commonly is used for remote areas of the grid [2]. Important parameters considered on small- scale wind energy conversion system (WECS) are low equipment cost and maximum efficiency. To convert wind energy into electrical energy, a wind turbine system consisting of blades, generators and power electronic is required. There are several technologies used to convert wind energy. However permanent magnet synchronous generator (PMSG) is mostly used due to high reliability, low maintenance, and high performance [3]. In addition, the PMSG can be used without a gear box to reduce costs and losses [4, 5]. The output power generated by the wind turbine (WT) system depends greatly on wind speed that is the ever-changing and unpredictable. To improve the efficiency of wind turbine systems, WT must work at maximum power point at any wind speed. Therefore, it takes a controller to extract optimum power on WT. WT will work at the optimum power point if the generator is working at optimum speed. Optimum power extraction on WT can be done through setting duty cycle on dc/dc converter [6].

Several methods have been developed to extract the optimum power of WT: tip speed ratio (TSR), optimal torque control (OTC), Perturb & Observe (P&O), artificial intelligent and fuzzy logic. Compared to TSR, OTC produces better performance [7]. However the use of TSR and OTC methods requires mechanical sensors to detect wind speeds and generator parameters thereby reducing accuracy and increasing system costs. The P&O method is the most widely implemented method because it is simple and does not require knowledge of wind speed and WT parameters. However, this method is difficult to follow the rapid changes in wind speed and cause oscillations under steady conditions [8, 9].

The use of fuzzy logic controllers produces better output power through setting the pitch angle. Compared to the PI controller, the PI fuzzy controller produces greater range resulting in better response and results in smaller power fluctuations [10]. But the use of pitch angle controllers not only disrupts peak power search strategy but also increases the stress on the blade. Fuzzy logic control was implemented to extract

optimum power based on output power of rectifier and PMSG rotation speed. But in this algorithm still require tachometer for measurement of PMSG rotation speed so that system cost increase [11].

In this paper, the proposed fuzzy logic to extract optimum power on PMSG wind turbine through setting duty cycle of buck converter without using mechanical sensor. Wind speed and turbine parameter are not required to develop fuzzy logic algorithm. The optimum power at each wind speed change is determined by the resulted current and voltage of the rectifier circuit. The performance of fuzzy algorithm is tested and compared to the P&O method with wind speed change.

II. MODELING OF PMSG WIND TURBINE

In this research, the WT system consists of a PMSG

connected to the blade, three phase uncontrolled rectifiers,

buck converter, controller, and load, as shown in fig. 1. PMSG

is connected with rectifier that will convert AC signal into DC

signal. To extract the optimum power in wind turbines, the

PMSG must work at optimum rotor speed through setting the

duty cycle of buck converter.

The wind turbine characteristic curve is shown in Figure 2 where at any given wind speed, the WT will have a certain optimum value as well. The greater the wind speed, the greater the power generated.

B. PMSG Modeling

One of the most commonly used generator types is the PMSG which is a regular synchronous machine where the DC excitation circuit is replaced with a permanent magnet to remove the brush. PMSG is more widely used because of better reliability, higher performance, small inertia moments and low maintenance costs. Dynamic model of PMSG can be expressed by using equivalent circuit dq that can be expressed by [5]

Where ids is the d-axis stator current(A), iqs is the q-axis stator current(A), vds is the stator voltage on the d-axis(V), vq is the stator voltage on the q-axis (V), Rs is the winding resistance (Ω), Ld is the winding inductance on the d-axis (H), Lq is the inductance winding on the q-axis (H), and p is the poles number. λqs and λds are flux stator of d-axis and q-axis.

Buck converter is composed by an inductor, diode,

capacitor and insulated gated bipolar transistor (IGBT) that

functions as a switch, as shown in Fig 3. Buck converter is

connected to the generated voltage of the rectifier and will

produce a smaller than the input voltage. When the IGBT

switch is closed, the diode will reverse bias and the current on

the inductor will rise linearly. While at IGBT off, the diode

will be active and the inductor will be discharged so that the

stored energy flows through the diode to the load. The IGBT

activation depends on the duty cycle on the given PWM pulse

so that the average output voltage of the buck converter (Vout)

can be expressed by

(10)

Where Vdc is output voltage of rectifier and D is duty cycle.

The output power that is delivered to the load can be

expressed by

=

(11)

Where Io is output current of converter and RL is load

resistance. Based on eq.11 and eq.10 can be expressed by

(12)

If the power losses on the converter are very small and

negligible then the output power will be equal to the input

power so

(13)

Therefore input resistance of buck converter (Rin) can be

expressesd by

(14)

Based on equation 14, the input resistance of the buck

converter depends on the duty cycle. Decreasing the duty

cycle will increase the input resistance of the buck converter

so that the converter input current will decrease which is

proportional to the decrease in the resulted current of PMSG

and the electromagnetic torque. The decrease in PMSG torque

will increase the PMSG rotor speed. Therefore setting the

PMSG rotor speed to operate at optimum speed can be done

through setting duty cycle on buck converter.

III. OPTIMUM POWER EXTRACTION CONTROLLER

To extract the optimum power on a PMSG wind turbine system, it takes a controller that will set the WT to work at the optimum rotor speed. Several methods have been developed to control maximum power extraction on WT. In this research, fuzzy logic has been developed to extract maximum power and its performance will be compared with P&O method.

A. Perturb&Observe (P&O) Method

The P&O method is one of the algorithms to extract optimum power in wind turbines at certain wind speeds. This method has been widely implemented because it is simple and easy to implement. The use of the P&O method does not require an anemometer for wind speed measurement, does not require knowledge of wind turbines and generator characteristics. The maximum power value of WT is obtained by controlling the duty cycle of the buck converter. The P&O

method works based on changing the control variable in small size and observing the change of the target function until the slope reaches zero.

Fig 4 describes algorithm of P&O method, where P&O method observes changes in rectifier output power (Pdc),

output voltage of rectifier (Vdc), and slope

to generate

duty cycle with constant step size (∆D). if

> 0 then the

operating point is on the left of the maximum power point (MPP) so that the PMSG speed must be increased by

decreasing the duty cycle (D) by ΔD. Conversely, if

<

0 then the operating point is on the right side of MPP so the PMSG speed should be decreased by increasing the D value. In this paper, the step size uses 0.01 and the rectifier output power is obtained based on the measurement of voltage and current that is generated by rectifier.

B. Fuzzy Logic Controller

Fuzzy logic was first found by Lotfi Zadeh in 1965

consisting of three stages of fuzzification, rule base look up

table and defuzification. Fuzzification is a process that

converts the numeric values of inputs into fuzzy numbers with

values between 0 and 1 using the fuzzy membership function.

The fuzzy rule is the fuzzy rules that relate two or more fuzzy

variables and defuzzification is the process of converting

fuzzy number values into numerical output values

In this paper, FLC is used to extract optimum power

through controlling duty cycle of buck converter. Therefore,

FLC output is a duty cycle (D) consisting of 5 membership

functions: negative small (NS), small (S), Zero (Z), Big (B)

and Positive Big (PB), as shown in Fig. 5. While the FLC

input consists of the resulted power change of the rectifier

(ΔPdc) and the generated voltage change of the rectifier (ΔVdc).

Each input variable consists of 5 membership functions:

negative small (NS), small (S), Zero (Z), Big (B) and Positive

Big (PB), as shown in Fig 6. The fuzzy rule shows the

relationship between input variables (ΔPdc and ΔVdc) and

output variables (D) arranged based on the wind turbine's

characteristic curve. If the value of ΔPdc is positive and ΔVdc

has a positive value then the wind turbine operates to the right

of the maximum power point so that the rotor speed must be

increased by decreasing the duty cycle. The fuzzy rules used

in this study are shown in Table 1 and Fig 7 shows flowchart

of FLC. FLC rule uses max-min method for inference engine.

The defuzzification process will change the fuzzy value of the

duty cycle to a numeric value with range of 0 - 1. The

defuzzification process uses the center of gravity method.

IV. RESULT AND DISCUSSION

Table 2 shows the PMSG wind turbine system

parameters. The performance of FLC to extract the optimum

power has been tested using Simulink and compared with

P&O method. FLC has been tested with a constant wind speed

of 10m /s and wind speed that is varied from 6.5m /s to 9.5m/

s.

P&O method, as shown in Fig 8.a. Therefore, the generated

power that can be extracted by FLC is also greater than the

P&O method. FLC performance is better because the P&O

method produces greater power fluctuations and oscillations

under steady state conditions. At wind speeds of 10 m/s, the

use of FLC can extract power of 4200W while the P&O

method is 3700W.

V. CONCLUSION

Fuzzy logic controller to extract optimum power for stand

alone PMSG wind turbine using buck converter has been

presented. The proposed method doesn’t require mechanical

sensor and wind speed measurement so it can reduce system

costs and more efficiently. FLC performance has been tested

through simulation and compared with P&O method. Based

on the simulation results, FLC has better performance, where

FLC can capture greater output power than P&O method. In

addition, FLC can extract optimum power to wind speeds

variation and generate no oscillations. Future research, we will

develop FLC algorithm for output power smoothing on wind

turbine system so that it can produce constant power as needed

although wind speed fluctuates.
