风光不确定条件下考虑双边交易的配微电网协同规划
Collaborative planning of distribution-grid and micro-grid considering bilateral transactions under wind-solar uncertain conditions
摘要
Abstract
In the emerging electricity market,bilateral transactions are conducted between distribution-grid operators and micro-grid operators.Under the uncertainty caused by the large-scale integration of wind and solar generation,the cooperation game between the distribution-grid and the micro-grid is analyzed at the planning level.The impact of multi-agent bilateral energy transactions is considered in this approach.To address the multiple non-convexities in traditional coordinated planning of distribution-grid and micro-grid,an alternating optimization-based strategy is proposed.Through the alternating optimization process,the discontinuous coordinated planning problem is transformed into a bi-level iterative solving process.In the upper level,Nash bargaining is applied to determine the traded electricity and payment strategies within a convex subset generated by the lower level.In the lower level,local individual planning problems are solved using trading variables obtained from the upper level.The market-clearing problem is decomposed into two subproblems,electricity transaction and payment settlement.The alternating direction method of multipliers is used sequentially to solve these subproblems.Case simulations on the IEEE 33-bus system demonstrate that the proposed model effectively enhances the operational benefits for both trading parties.关键词
