METHOD FOR THE COMPUTER-AIDED CONTROL OF ONE OR MORE REGENERATIVE ENERGY PRODUCTION INSTALLATIONS IN AN ELECTRICAL POWER SUPPLY SYSTEM

摘要

The invention relates to a method for the computer-aided control of one or more regenerative energy production installations (RG) in an electrical power supply system (PG) that contains a plurality of network nodes (N1, N2,..., N6) that are connected to one another via power supply lines (PL) and that feed electric power into the power supply system (PG) and draw electric power from the power supply system (PG), wherein the regenerative energy production installation or energy production installations (PG) are network nodes (N1) for feeding electric power and each comprise an energy store (C) for buffer-storing energy that can be fed into the power supply system (PG) as electric power. The method according to the invention is distinguished in that the energy production installations (RE) in the power supply system are operated as a voltage source, wherein the AC voltage (U_AC) on the energy production installation (RE) is regulated such that the quantity of energy in the energy store (C) remains above a maximum power energy value at which the maximum electrical active power (P_m) is produced by the respective regenerative energy production installation (RE). This ensures stable operation of the power supply system without system failures. The method according invention is preferably used for regenerative energy production installations in the form of photovoltaic installations or wind power installations.
