Evaluation method for high-dimensional complementarity of hydro-wind-solar energy considering volatility
摘要
Abstract
Quantifying hydro-wind-solar energy complementarity is crucial to planning and optimal dispatch of a co-generation system.However,previous evaluation indexes for the complementarity paid less attention to the three-dimensional complementary capacity of hydro-wind-solar energy,and they were often used to either consider only the overall trend or the amount of change in a continuous period of the power output sequence,or they neglected the effect of fluctuating phase differences,lowering the accuracy of quantification in a variety of scenarios.This paper examines the correlation of hydro-wind-solar energy fluctuations in depth,and presents a new multidimensional,multi-timescale complementarity evaluation index by categorizing fluctuation states in consecutive periods.Then,we verify this index for several typical scenarios and show its accuracy in quantifying complementarity of hydro-wind-solar energy sequences,and its superiority by comparing the results with those of the previous complementarity indexes.Finally,application of the new index to regional wind-solar planning is demonstrated in a case study of a comprehensive development base for hydro-wind-solar integrated renewable energy in the Wujiang River basin.For this base,optimal ratios of the wind-solar installed capacities are given in different time scales.关键词
