Abstract

The current trend of renewable integration in networks is being fueled in large part by the inescapable rise in electrical power consumption, the depletion of conventional power generation resources, and the widespread concern about global warming. One of the most significant issues brought on by this developing trend is the overvoltage produced by distributed generation units that are interfaced at the consumer end and power injected at random nodes. Contrary to typical grids' preset power flows, this results in bidirectional power flows, which need the use of a modern, coordinated, and reliable voltage control method with a minimal amount of communication infrastructure. To stop the voltage variations brought on by excessive solar integration in distribution networks, a centralized based Volt/VAR regulating strategy is proposed. To evaluate the effectiveness of the suggested system, we employ MATLAB Simulink on an IEEE-15 bus standard. The results show the superiority of the centralized strategy on the decentralized one.
