Virtual power plant
Renewable energy should become increasingly in future as an alternative energy in the power plant. To important structural changes that are necessary to decentralised energy supply infrastructure. Energy should be "produced", where and exactly when you need it.
The ABG FRANKFURT and driven by common energy transformation HOLDING m Nova AG. For this, they have launched first virtual power plant with CHP in Frankfurt April 2012.

In the compound of a virtual power plant, the fluctuating electricity generation is balanced by renewable energies. Only through the virtual power plant, renewable energy thus become a real alternative, which can ensure the security of supply that is familiar in Germany.

The building blocks of a virtual power plant are quite real. More accurately, one would have to actually speak of power a "virtual plant". Through the merger of many small producers it bundles many electricity generating capacity as power in a virtual plant. So, virtual power plants with sufficient size can replace even nuclear power plants.

At the start of the virtual power plant, the ABG and Mainova connect first ten CHPS in various properties of ABG with State of the art information and communication technology. The high-efficiency, gas-powered small engines of power plants produce heat and electricity at the same time. So far, they produce the electricity when heat is needed in the House. First, a central control to combine the services of the individual facilities and closely align them.

The virtual power plant stands by ABG and Mainova from the approaches of competitors also, that allows the network to integrate existing CHP, regardless of manufacturer, type and year of manufacture. In Frankfurt, there are around 200 CHP plants with a total power of about 25 MW according to research of the energy unit Frankfurt, they could be incorporated into the virtual power plant. The Energy Department also estimates the additional potential of CHP in Frankfurt with 40 MW. CHP's have the advantage that they produce high-efficient heat and electricity and can be supplied with bio natural gas in the future.

The central control of the cogeneration plants to move the generation of heat as possible on the times when power in the grid is required. This temporal decoupling is carried out through the hot water storage tank. The heat supply of the tenant is not affected.

The virtual power plant of the Mainova and ABG is expected to grow. In addition to CHP of other operators, electricity consumers such as heat pumps, ventilation systems, etc. in the composite can be recorded in the future. Electromobility makes it possible to go in the future with renewable energy on the road. Electric vehicles should be loaded but then when the renewable energy available, if the wind blows and the sun shines. The integration of charging stations in the virtual power plant will ensure that.

The control of the virtual power plant was implemented in a partnership for development of the ABGnova, the Stadtwerke Aalen and the Lübeck software company cbb. It is a development project that is already well advanced.

The advantages of the solution are:
•Power generation is done with high-efficiency cogeneration electricity demand.
•It is suitable for small systems.
•The integration of electrical consumers is possible: ventilation and air conditioning, electric water heater, electric vehicles, heat pumps, etc.
•The solution is independent of the CHP type or manufacturer.

The virtual power plant used in electricity prices at the Leipzig Exchange EEX as an indication for the electricity supply from wind and Sun. About the timetable, power generation should be moved to the "most expensive" hours. This increases the market price of electricity. The difference between the highest and lowest daily prices varies greatly. Actually, the lowest prices can be negative. A prize shot exists throughout the year between 11: 00 and 12:00, during the winter months there is a price point between 17: 00 and 20:00.

Function of the virtual power plant:
•The headquarters of the virtual power plant compares the price of electricity for the following day with the compensation under the law on cogeneration and determined periods of time for the electricity.
•In software, the CHP can be created with their special properties and are affiliated to groups.
•Without control signal of the headquarters, the CHP are driven by their internal control according to the respective needs of heat.
•The Headquarters on a roadmap pretending when the CHP in operation should be, be "off" or to flush the memory for later operation of cogeneration plants.
•The electricity produced is captured a smart meters.
•Electricity trading will determine the additional proceeds, which was achieved by the time optimized driving.

Another advantage of the virtual power plant is that this infrastructure allows for more possibilities of use. So the power of virtual power plants can be used, not only for direct marketing, but also the provision of balancing energy to the mains load optimization or balance circuit optimization.

Electric hot water heater play an important role in the concept. It excess wind power to be generated using these in future heat instead of natural gas.
