摘要

 摘 要:随着中国新一轮电力体制改革的加速推进,区域中长期交易市场逐渐成熟,现货市场成为深化电力改革推进的突破点。针对现货市场下的节点边际电价展开研究,基于各省电改政策分析了最优潮流下的节点边际电价计算方式,采用预测-校正原偶内点法进行优化,并通过Psat搭建仿真模型进行验证。基于阻塞对节点边际电价的区域影响特性,考虑空间分布、发电企业报价和节点边际电价,提出一种电力市场分区策略。经仿真验证,所提策略可以较好地应用于现货市场分区,能够明确反映电力市场价格信号,为发电企业和电力用户的投资提供方向,促进电力现货市场的有序发展。
 

Abstract

ABSTRACT:    With the acceleration of electricity market reform in China, the regional long-term electricity market gradually matures, and the spot market is becoming the breaking point of the deepen reform of electric power. This paper researches the locational marginal price (LMP) in spot market. Based on the electric reform policies of each province, we analyze the calculation method of LMP under the optimal power flow, use the prediction-correction original-interior-point method to optimize it and build a simulation model in Psat to verify it. Based on the regional influence of blockage on LMP, this paper proposes a partitioning strategy for spot market    by considering the regional distance, the bidding of power generation enterprises and the LMP. Simulation results show that the proposed strategy can be applied to spot market partition, which can clearly reflect the price signal of electricity market, provide investment direction for power generation enterprises and power consumers, and promote the orderly development of power spot market.
