Method for optimizing feed power and stability in public power supply network, involves feeding power contributed to photovoltaic systems over inverter as reactive power fed into supply network or related to power in supply network

摘要

The method involves notifying momentary freely available capacitance of an inverter for supply or delivery of reactive power to a control room (15), where the inverter works based on electronic components. Power contribution for regenerative photovoltaic systems (7, 9, 11) is determined from received data for idle reactive power capacitance by the control room. Power contributed to the photovoltaic systems is fed over the inverter as the reactive power fed into a public power supply network (1) or related to power in the supply network.
