Voltage Control of Distribution Networks with Distributed Generation using Reactive Power Compensation

Abstract

Voltage profile of distribution networks with distributed generation are affected significantly due to the integration of distributed generation (DG) on it. This paper presents a way to control voltage of distribution networks with DG using reactive power compensation approach. In this paper, the voltage control approach is shown based on the worst case scenario of the network. To keep the voltage profile within the specified limits, it is essential to regulate the reactive power of the compensators. Finally, based on this concept, a static analysis is done on a 15- bus Japanese distribution system, called Kumumoto system where the system is modified with the inclusion of distributed wind generators, photovoltaics, and synchronous generators.
