Stability and Capacity Analysis of Power Quality Conditioner in Microgrid

Abstract

Abstract: According to the power quality problem of microgrid based on new energy distributed generation, this paper introduced a kind of comprehensive power quality conditioner scheme. In the scheme the conditioner series part is used to suppress distributed new energy generation intermittence, and the series side is used to eliminate the harmonic current brought by nonlinear load into the microgrid. On this basis, the paper analyzed the stability of the system and the relationship between the conditioner capacity and related parameters, and simulations were performed. The results show that the equivalent parallel resistance is an important factor on the system stability; the voltage volatility is a key factor to affect seriesparallel side conditioner capacity. At the same time, the paper provide the condition of minimum capacity. The results provide guidance for the actual device design and related parameter selection and have certain theoretical significance and practical value for further study.
