説明
<p>In power systems, it is necessary to properly manage the reactive power to maintain the voltage within a desired operating range. The voltage in an Extra High Voltage (EHV) system has been maintained by using voltage controllers (Synchronous Generator (SG), Shunt (Shunt Reactor), SC (Static Condenser), On Load Tap Changer (OLTC), etc.). Currently, the introduction of Distributed Energy power Resources (DER) is increasing rapidly and the number of conventional SGs in service which have supported voltage in power systems are being decreased. Hence, it is highly required to realize more flexible voltage regulation even with the DER integration in order to avoid voltage deviation caused by insufficient reactive power support from the conventional SGs.</p><p>This paper proposes the Centralized Voltage and Reactive Power (Q) Control (VQC) which can manage the control setpoints of Local VQC in substation. The proposal controller monitors the short circuit capacity and updates the dead band width depending on the step size of the voltage control. The control effect of the Local VQC combined with the proposal controller was verified through numerical simulations by using a developed VQC simulation software.</p>
