Abstract

Photovoltaic power generation, with the advantage of renewable energy and convenient installation, has been widely used in distributed generation in distribution network as the technology gradually developed. Grid-connected photovoltaic power generation station not only changes the structure single terminal power supply distribution network, affect the operation of distribution network due to its fluctuant and intermittent characteristics. As grid-connected photovoltaic power station adopts power electronic converter for the connection to distribution network, the harmonic voltage and current as well as the DC components are inevitable. Therefore, the impact analysis and the comprehensive evaluation of grid-connected photovoltaic power station are studied.The main contents are as follows: 1: Based on the multiple CPUs embedded measurement and evaluation system designed for the grid-connected photovoltaic power generation station, a positive and negative effect index is proposed for its comprehensive evaluation. With FFT as basic power measurement algorithm and adopted DSP computing unit, data manage unit and analysis unit, a real-time calculation of positive and negative effect index is realized. 2: Common weights of the index are determined by DS/AHP method with incomplete information, and then the weight synthesizing of positive and negative effect index are conducted through penalty-incentive balance functions respectively. The comprehensive evaluation results are generated by the method of grey relation analysis.
