摘要

分布式光伏余电上网政策性补贴给微网的优化运行带来了新的机遇与挑战。以微网运行的净收益最大化为目标，分析了光伏余电上网补贴对于微网出力决策的影响，建立了考虑光伏余电上网的微网系统综合决策调度模型。采用序列二次规划(SQP)算法进行求解，以实际微网系统为例，对比分析了含光伏的微网分别接入居民区、商业区、工业区等不同场景下的出力及经济效益的优劣，并评估了光伏容量及上网电价对收益和成本的影响。

Abstract

Surplus distributed photovoltaic (PV) power sold to the grid with a new compensation price brings opportunities and challenges for optimal microgrid operation. This paper aims at maximizing the net operating earnings of a microgrid. Firstly

the impact of PV compensation price on the operation of microgrid is analyzed

and a decision-making scheduling model considering the subsidies of PV surplus power is established. Then the sequential quadratic programming (SQP) algorithm is utilized to solve the established model. Finally

some case studies are done based on the real data from an actual microgrid system

the differences of microgrid economic benefit with the gird accessed to residential

commercial and industrial areas are compared respectively. The sensitivity analysis is also performed to study the impact of PV capacity and on-grid price on the economic benefits of a microgrid.
