规模化屋顶光伏接入配电网的建设决策

Construction decision of large-scale roof top photovoltaic integrating into distribution network

围绕规模化屋顶光伏的选优建设问题,提出一种规模化屋顶光伏建设方案的综合评价方法。基于屋顶光伏建设的相关方分析,从供电影响侧、环保侧、经济侧、市场侧角度构建一套适用于屋顶光伏建设决策的综合评价指标体系,供电影响侧考虑并网运行质量与匹配度,环保侧体现绿色低碳效益,经济侧关注投资建设效益,市场侧反映应用参与度与接受度;采用层次分析-G1结合赋权法、改进的基于指标相关性的指标权重确定法分别求解指标主、客观权重,并通过改进的最小偏差组合赋权模型确定指标综合权重,采用优劣解距离法完成方案的评价与决策。算例仿真结果验证了所提方法的有效性。

Focusing on the optimization problem of large-scale roof top photovoltaic construction,a comprehensive evaluation method for the construction scheme of large-scale roof top photovoltaic is proposed.Based on the analysis of relevant parties in roof top photovoltaic construction,a comprehensive evaluation index system suitable for decision-making of roof top photovoltaic construction is built from the perspectives of power supply influence side,environmental protection side,economy side,and market side,the quality and matching of grid-connected operation are considered at the power supply influence side,the green and low-carbon benefits are reflected at the environmental protection side,the investment and construction benefits are focused at the economy side,and the application participation and acceptance are reflected at the market side.The analytic hierarchy process-G1 combination weighting method and an improved criteria importance through intercriteria correlation method are respectively adopted to solve the subjective and objective weights of the indicators,and the comprehensive weights of the indicators are determined through an improved minimum deviation combination weighting model,the technique for order preference by similarity to an ideal solution is adopted to complete the evaluation and decision-making.The simulative results of examples verify the effectiveness of the proposed method.
