    III. COMPUTATIONAL INTELLIGENCE METHODS

    Computational intelligence (CI) is the study of adaptive mechanisms to enable or facilitate intelligent behavior in complex, uncertain and changing environments. These adaptive mechanisms include those bio-inspired and artificial intelligence paradigms that exhibit an ability to learn or adapt to new situations, to generalize, abstract, discover and associate [2]. The typical paradigms of CI are illustrated in Fig. 1 [3]. These paradigms can be combined to form hybrids as shown in Fig. 1 resulting in Neuro-Fuzzy systems, Neuro-Swarm systems, Fuzzy-PSO systems, Fuzzy-GA systems, Neuro-Genetic systems, etc.

    Other advanced CI techniques include adaptive critic designs [4], reinforcement learning and approximate dynamic programming [5]. Adaptive critic designs (ACDs) use neural networks based designs for optimization over time using combined concepts of reinforcement learning and approximate dynamic programming [4-5]. ACDs use two neural networks, the critic and action networks, to solve the Hamilton-Jacobi-Bellman equation of optimal control. The critic network approximates the cost-to-go function J of Bellman’s equation of dynamic programming (1) and is referred to as the heuristic dynamic programming (HDP) approach in ACDs,

    where γ is a discount factor between 0 and 1, and U(t) is a utility function or a local performance index. The action network provides optimal control to minimize or maximize the cost-to-go function J. Fig. 2 shows the HDP based ACD approach. There are several other members of the ACD family that vary in complexity and power [4].

    IV. CI METHODS FOR SMART GRIDS

    CI and advanced CI techniques have been applied to solving challenging problems today in electric power systems. CI methods can contribute to electric power systems and smart grids in a number of ways as illustrated in Fig. 3. A few of these problems addressed by author and other researchers are discussed below. Many of these solutions are directly applicable to smart grids – modernization of the grid using full digital technology.

    As known widely, the nonlinear modeling of the time

    varying dynamics of an electric power system is still a challenge using classical techniques but computational intelligence paradigms such as neural networks have been shown to successful model the nonlinear dynamics offline or online. Multilayer perceptrons, radial basis functions (RBFs), simultaneous recurrent neural networks (SRNs) and echo state networks have all been reported very effective models for the design of nonlinear, adaptive and/or optimal controllers such as for generator excitation systems, turbines and FACTS devices [6-8]. Most of the identification/modeling techniques are based on supervised learning techniques as illustrated in Fig. 4. Neural networks can be trained online to track the

    The increasing complexity and highly nonlinear nature of electric power systems today requires a fast and an accurate online monitoring system, a wide area monitor (WAM), for effective control of power networks with an adaptive wide area controller (WAC). Similar approaches as illustrated in Fig. 4 are suitable for WAM [9, 10]. WAM is essential for smart grids to the functions mentioned in Section II such as self-healing, fault-tolerance and dynamic optimization.

    As several generation sources connect and disconnect to a smart grid, it will become necessary to identify the dynamics of the system at any given point in time and adjust the parameters, and maybe even the structures, of the local and auxiliary controllers. Preliminary results of an external damping controller on a traditional power system have been demonstrated in a real-time on a laboratory platform [11, 12].

    Furthermore, it has been shown that critic networks based on advanced neural network architectures, such as simultaneous recurrent neural network, are capable of optimizing the performance multiple local controllers on generators and FACT devices to improve system damping [13]. SRNs are powerful neural networks for prediction based on recurrence and have been shown to overcome the varying time delays in the communication channels for WAC. The real-time implementation of a two-area four machine power system shown in Fig. 5 was carried out at the author’s lab - Real-Time Power and Intelligent Systems Laboratory at Missouri University of Science and Technology. Despite varying time delays, a system damping higher than that provided by local controllers (see Fig. 6) can be guaranteed with WAC over a significant range of delays [14]. This is possible due to multi-step prediction capabilities of SRNs.

    Wide-area coordinating control is becoming an important issue and a challenging problem especially when large wind farms are connected to the power grid. An optimal wide-area monitor based on a RBF neural network has been developed in [15] to identify the input-output dynamics of the nonlinear power system. Its parameters are optimized through particle swarm optimization. Based on the WAM, a WAC is then designed by using the dual heuristic programming (DHP) method and RBFs, while considering the effect of signal

    transmission delays. The WAC operates at a global level to coordinate the actions of local power system controllers including those on the wind farm. Each local controller communicates with the WAC, receives remote control signals from the WAC to enhance its dynamic performance, and therefore helps improve system-wide dynamic and transient performance.

    Control of electric power systems relies on the availability

    and quality of sensor measurements. However, measurements are inevitably subjected to faults caused by broken or bad connections, bad communication, sensor failure, or malfunction of some hardware or software. These faults in turn may cause the failure of power system controllers and consequently lead to severe contingencies in the power system. To avoid such contingencies, a sensor evaluation and (missing sensor) restoration scheme (SERS) by using auto-associative neural networks (auto-encoders) and particle swarm optimization. Based on the SERS, a missing-sensor-fault-tolerant control (MSFTC) was developed for controlling a static synchronous series compensator (SSSC) connected to a power network. This MSFTC improved the reliability, maintainability and survivability of the SSSC and the power network. The details of this work are presented in [16]. Such fault-tolerant technologies will be needed in a smart grid to improve its reliability and security.

    The future grid will have the capability where plug-in vehicles can charge from it or discharge to it. An intelligent method for scheduling optimal usage of energy stored in these vehicles is necessary. The batteries on these vehicles can either provide power to the grid when parked, known as

    vehicle- to-grid (V2G) concept or take power from the grid to charge the batteries on the vehicles, known as grid-to- vehicle (G2V). Finding optimal times to charge or discharge in order to maximize profits to vehicle owners while satisfying system and vehicle owners’ constraints was studied. In order to do this, binary particle swarm optimization was applied in [17]. Price curves from the California ISO database are used in this study to have realistic price fluctuations. Different fleets of vehicles are used to approximate varying customer base and demonstrate the scalability of parking lots for V2G. The results for consistency and scalability are included. Fig. 7 shows a typical parking lot for plug-in electric vehicles connected to the utility grid. Table I shows the profit made by the vehicle owners based on a PSO scheduling on a given day. More details on this work are given in [17].

    V2G can reduce dependencies on small expensive units in the existing and future power systems as energy storage that can decrease running costs. It can contribute to efficient management of load fluctuation, peak load; however, it increase spinning reserves and reliability. As number of gridable vehicles in V2G is much higher than small units of existing systems, unit commitment (UC) with V2G is more complex than basic UC for only thermal units. Particle swarm optimization was proposed in [18] to solve the V2G scheduling problem, as PSO can reliably and accurately solve complex constrained optimization problems easily and quickly without any dimension limitation and physical computer memory limit.

    Climate dioxide (CO2) is now widely accepted as a real condition that has potentially serious consequences for human society and industries need to factor this into their strategic plans. The power and energy industry represents a major portion of global emission, which is responsible for 40% of the global CO2 production followed by the transportation sector (24%) [19]. Economic growth does not have to be linked to an increase of GHG emissions and can be attained in addition to the usage of renewable energy sources by using energy efficiency technologies for power system generation, transmission, and distribution. The development of intelligent energy-efficient control technologies will both soften negative effects of the climate change on the economy and enhance energy security. A summary of the impacts on CO2 reduction by the applications of intelligent techniques has been reported in [20]. Furthermore, UC with V2G can take into account besides fuel cost minimization, the reduction of emissions by explicitly factoring cost of emissions in the cost function. Table II shows some typical results on a small 10-unit and 20-unit systems with 50,000 and 100,000 gridable vehicles. Intelligent optimization become very useful as the parameters to optimize grows enormously.

    Maintenance scheduling of generating units and other elements in a power system is an important task, and plays important role in the operation and planning activities of the electric power utility and the future smart grid. Computational intelligence tools are excellent for determining optimal maintenance schedules [21]. In a smart, resources need to be scheduled including real and reactive power generation, and energy storage.

    Other computational intelligence applications for smart grid include forecasting dynamic loads and electric energy. Typically, amount of load is dependent on a number of factors including time of the day, day type (weekday or weekend), temperature, humidity, season and location. Neural networks have been extensively studied and shown to provide accurate load predictions [22, 23]. Neural networks have also shown to be promising tools for wind and solar energy predictions [24, 25]. When alternative sources of energy are connected to the power grid, be it wind farms or plug-in vehicles, dynamic load and electric energy at a given time needs to be predicted in order to carry out an efficient and economical operation of a smart grid.

    There are several other CI applications for the smart grid including energy and power flow management algorithms. Adaptive critic designs and PSO-based fuzzy logic have been demonstrated to carry out optimal energy dispatch in a grid independent photovoltaic system [26]. Numerous researchers have reported on the successful use of CI approaches for voltage and reactive power control [27]. Reconfiguration of distribution systems have carried out with PSO and genetic algorithms. CI techniques have the potential to carry out dynamic reconfiguration and restoration of terrestrial and industrial power systems [28] after small and large disturbances. All these problems and solutions are applicable to smart grids.

    V. CONCLUSIONS

    The electric power grid is rapidly growing and demanding new technologies for efficient, reliable and secure operation and control as the demand for electricity increases. The complexity of a smart power grid is much more than that of the traditional power grid as time-varying sources of energy and new dynamic loads are integrated into it. Advanced intelligent techniques are required to handle the smart grid operation in an efficient and economical manner. The potentials of computational intelligence paradigms have been demonstrated for various challenges in the traditional power system. Such techniques are promising solutions to deliver the expectations of a smart grid.
