Economy and calculations If 4 million households are provided
with smart power cells, the total price of generators, all
equipment and software will be equal to the nuclear power station
price. Actually, the power is also approximately the same. *Data
book According to electricity tariff in the USA (0.0966 $/kWh), if
such power cell with a power of 10 kW every day during 6 hours
transmits energy to the power grid, its owner will have an income
of 2115.5 $ in a year. That is all investments will have been
returned less than in 5 years. *Data book According to the feed-in
tariff in Europe (0.42 $/kWh), pay-back period is only one year.
*Data book Problems and assumptions Nowadays development of
renewable energy sources follows two different pathways: 1.
Construction of high-powered stations, based on renewable sources
of energy. Problems: Such stations occupy vast areas. May interfere
in our lives (e.g. wind mills). Have problem with energy
accumulation and storage. Require construction of the new power
lines and substations. They need maintenance and operating
personnel. 2. Usage of renewable energy sources in private
households. Problems: Existing devices dont offer integrated
solving for the problem of energy generation, accumulation,
conversion and informational link between each consumption point
and energy supply provider. Such energy generation is uncontrolled,
devices unbalance grid in peak time. Hypothesis Amount of renewable
energy produced in households can be increased significantly only
by creation of web-like power nets with informational and energetic
synchronization of their elements. Aim of the project To increase %
of renewable energy sources without any power network degeneration
by implementation of the Internet web based electric grid
structure. To develop and test the model of low-cost integrated
device (smart power cell) for household bidirectional energetic and
informational connection to the power network. To evaluate economy
of such device implementation. Existing systems and their
disadvantages Cannot unite energy overflows in both directions. Do
not protect household from mains network deviations. Dont have
informational connection with other devices and energy supply
provider. Cant create isolated networks with some devices in the
event of the main grid collapse. Dont optimize energy overflows
technically and economically. The Idea To connect households to the
mains power lines by a special network of integrated devices (the
so called smart power cells), which could perform the following
tasks: Recieve energy from the power net and supply it to the
household with stable parameters. Store harnessed or mains power
grid energy (for example in the electric vehicle). Convert energy
produced by unstable generators such as solar panels and wind
mills. Transmit this green or stored energy to the power grid, to
the household and to the smart network depending on technical and
economical needs. Implement informational link with energy supplier
and other cells for economical and technical optimization. Smart
power cells connection to the grid is similar to computers
connection to the Internet (energy is redistributed as information
in the Torrent). How does the system work? Smart power cell
consists of three energy sources: mains power network; generator
(solar panels, wind or Stirling generator etc.); energy storage
(battery, electric vehicle) and two consumers: main power grid and
smart house power network. Energy flows are permitted at any
direction, in and out of the smart power cell, depending on the
system status and economic component, needs and resources. House
power network inverter works in one direction to the house power
network. Mains grid inverter transmits energy from either storage
or generator to the main power network. Pulse transformer inverter
transmits low voltage energy 12V (generator and storage) to high
voltage DC energy. All these processes are controlled by
microcontroller (including storage charge/discharge) depending on
economy (price of energy) or technical (power network stability)
demands. Conclusions - Increase of the green power constituent in
the main grid is possible by the implementation of the Internet
controlled smart cells system. - Tested that on demand some smart
power cells may create temporary isolated power systems in the
event of the main grid collapse. - Depending on the location
suggested system can be integrated with mains power grid or can
exist separately. - Such system will increase efficiency and
firmness of power net. It will reduce the risk of blackouts, help
to spare money on building huge power stations, save natural
resources, and prevent environmental pollution by decreasing
conventional power stations. - This idea will give rise to new
industries and require a large number of qualified personnel. -
Process of joining new power cells will improve system functioning.
Future project development Experimental part. To create power cells
samples with a power of 2, 5 and 10 kW. Test them in real life
conditions in combination with different types of renewable energy
sources. Develop new computer programs to connect power cells with
each other and with energy supply provider. Business part. Offer
business plans for the project, attract investors and create a
state program. ConventionalRenewable *1*2*3*4*5 fhghghghg
