Harmonic source identification of a distributed generator, and compensation of the voltage change caused by changing generation

Abstract

Energy industry is facing one of the biggest transition of its history. The decreasing amount of fossil fuels, the reduction of emissions, the rising energy prices all advert renewable energy resources. The penetration of distributed generation has already begun, but the integration into the old network structure is still in its infancy; the technological change is not yet followed by the needful aspect change. For this reason, extended investigation of the connection terms is indispensable. In the present paper two aspects are examined. First, a computer model is created, and the verification process is done, using the method of harmonic source identification. The second part of the paper focuses on the steady voltage change caused by the connection of the generator. After simulations, the authors set a potential course to solve the problem, using only the built-in power electronic devices.
