Simulation results of cogeneration units as system reserve power source using multiagent modeling

The paper is dealing with the modeling and simulation of distributed generation units in order to integrate them into the power system control. The cogeneration units have been widely spread during the last decades, even in Hungary. These units are not involved yet into the system control. Their integration should be carried out as soon as possible in order to provide more controllable reserve energy for the Transmission System Operator. However several questions should be considered, and giving the proper answer is impossible without suitable modeling of the problem. A multiagent model was established to study the possibility of this integration. Several constraints are taken into account considering district-heating service, fuel consumption, legal regulation, outages and services. The economic studies proved the integration could be realized through financial motivation. The amount of reachable power would have been enough for system control in 2009. The amount and price of reserve power are influenced by several parameters, e.g. the actual season of year, the frequency and duration of controlling. Finally optimal selections of generation units are determined regarding a possible pilot project and for a real application in future.
