摘要
随着新能源的快速发展,多种清洁能源互补发电运行在电力系统中逐渐占据重要地位。本文提出了一种考虑多指标综合评价的多能互补方法。根据灰色预测模型及Weibull分布模型对光伏发电和风力发电进行功率预测,设计不同类型多能互补方案;分别建立能源负荷曲线差异度指标、能源组合经济指标和稳定性指标,并提出一种考虑多因素影响的综合评价方法。算例结果验证了所提多指标评价方法用于清洁能源互补方案选择的有效性。
With the rapid development of new energy,a variety of clean energy complementary power generation plays an important role in the power system.This paper presents a multi-energy complementary method considering multi-index comprehensive evaluation.According to the grey prediction model and Weibull distribution model,the power prediction of photovoltaic power generation and wind power generation is carried out,and different types of multi-energy complementary schemes are designed.Different index of energy load curve,economic index of energy combination and stability index are established respectively,and a comprehensive evaluation method considering the influence of multiple factors is proposed.The results of the calculation example verify the effectiveness of the proposed multi-index evaluation method in the selection of clean energy complementary schemes.
