考虑多限价约束的省间电力中长期集中交易综合评估方法OA

With the continuous expansion of inter-provincial medium-to-long-term electricity trading,it has become necessary to impose limits on market prices to standardize market operations and protect the interests of diverse market participants.Consequently,this paper proposes a comprehensive evaluation method for inter-provincial medium-to long-term centralized electricity trading that accounts for multiple price limit constraints.Firstly,based on current policy requirements and practical experience in inter-provincial electricity trading,a price limitation mechanism for centralized trading.Simultaneously,the coupling relationships across the bidding,clearing,and settlement phases are accounted for,and a multi-stage combined price restriction model and a clearing model for centralized trading incorporating these price limit constraints are constructed.Furthermore,a quantitative evaluation index system covering macro-level overall benefits,micro-level provincial benefits,and temporal coordination is established.Considering the interests of grid operators,electricity sellers,and end-users in inter-provincial trading,we propose an integrated evaluation approach based on Group Decision Analytic Hierarchy Process(AHP),Entropy Weight Game Theory-based Combined Weighting,and TOPSIS(Technique for Order Preference by Similarity to Ideal Solution).Finally,case studies validate the effectiveness of the proposed price restriction model,establish a ranking of different price-constraint schemes,and confirm the rationality of the methodology,thereby providing a decision-making basis for inter-provincial medium-to long-term electricity trading operations.
