  • METHOD FOR ACTIVE CONTROL OF FREQUENCY AND VOLTAGE IN A POWER SUPPLY GRID WITH DECENTRALIZED POWER SUPPLY SYSTEMS
    Publication number: 20140316604
    Abstract: The invention relates to a method for actively controlling in a feedback control at least one output parameter (fi, Vi, Pi, Qi) of a decentralized power generating unit (1) feeding power into a power supply grid (14) having a plurality of such decentralized power generating units, the power generating unit (1) being coupled to the grid (14) at a grid tied point (16). The actual resistance (Ri), reactance (Xi) and magnitude (|Zi|) of the impedance (Zi) of the power generating unit (1) at the tied point (16) is determined and a first quotient (Ri/|Zi|) between the resistance (Ri) and impedance magnitude (|Zi|) and a second quotient (Xi/|Zi|) between the reactance (Xi) and the impedance magnitude (|Zi|) is calculated. These quotients (Ri/|Zi|, Xi/|Zi|) are used for the feedback control of the at least one output parameter (fi, Vi, Pi, Qi).
