Using Solar Power Plant for Reactive Power Support
Öz
Reactive power compensation investments are made for energy production, transmission and distribution systems. Currently, electricity distribution companies invest in reactors, capacitors and magnetically controlled reactors for reactive power compensation. With these investments, transmission companies receive reactive power support from existing production plants within the scope of ancillary services. Nowadays, with the increase in distributed generation facilities such as solar power plants (SPPs) and wind power plants (WPP), the energy flow connected to the distribution grid has become bidirectional. In distributed generation facilities such as SPP and WPP, during hours when there is no production, the capacitive reactive originating from the conductors increases and the increase in production causes voltage rise in the region. In this study, the usability of SPPs for reactive power compensation was investigated in order to turn the disadvantages of distributed energy resources into advantages and to reduce compensation investment costs. For this purpose, necessary simulation studies were carried out to obtain reactive power support from a solar power plant connected to a transformer center in a electricity distribution region. Later, experimental studies were carried out by receiving reactive power support from the solar power plant in the region for seven hours. As a result, it has been emphasized that the reactive power support received from the solar power plant will reduce compensation investments.
