Performance Evaluation of Harmonic Current Summation Law Applying to the Wind and Photovoltaic Generation

The increasing penetration of renewable energy sources with nonlinear characteristics, such as wind and photovoltaic power plants, demands a clear procedure for harmonic current estimation on point of coupling of these sources. The summation law is widely used to estimate the total harmonic current in a coupling point between the network and a distributed generation. This is done for each harmonic order and the analysis is performed by mean harmonic currents provide by an individual wind turbines. In this work, the summation law will be analyzed by a wind park case study.
