A Hybrid Wind/Photovoltaic Power Supply System Based on Discrete Probabilistic Methodology
摘要
Abstract
A probabilistic methodology based quantitative capacity optimal configuration method of hybrid wind/photovoltaic power supply system is proposed. A discrete probability distribution model is established to represent the random variables in the system, including the uncertainty of power injections and the random failure of components. A multi-objective optimization model is proposed involving three contradictory objectives: minimization of major investment, power inadequacy and voltage deviation. An innovative probabilistic load flow algorithm is introduced for the purpose of fast probability computing while maintaining a relatively high degree of accuracy, which uses moments to calculate and convert cumulants and Gram-Charlier series to obtain probabilistic distribution functions of target variable. The parallel elitist non-dominated sorting genetic algorithm (PNSGA-Ⅱ) is introduced to search the Pareto-optimal solutions. Finally, a numerical example is provided to validate the applications of the proposed method.关键词
