Applying the Superposition Procedure for the Harmonic Sharing Responsibility between Renewable Energy Power Plants and the Network

Abstract

Abstract The increasing penetration of renewable energy sources with nonlinear characteristics, such as wind and photovoltaic power plants, demands a clear procedure for harmonic sharing responsibility between this new kind of generation and the network at the point of common coupling. In fact, there are in literature many procedures regarding the determination of responsibility for violating harmonic distortion limits. Among these proposals, the methodology based on the superposition principle has been one of the most promising procedures. In this context, the present paper is focused on a procedure that applies the superposition methodology to find the harmonic sharing responsibility between a wind power plant and the utility network. To exemplify this application, a case study is performed and analyzed.
