区域统一电力现货市场跨省资金平衡问题研究

A Study on Cross-provincial Blocking Imbalance Funding in the Regional Unified Electricity Spot Market

区域电力现货市场建设是构建全国统一电力市场的重要一环,南方区域已建设统一平衡的集中式区域电力现货市场,并开展调电结算试运行,而跨省阻塞不平衡资金的计算和疏导方式的合理性关系省间市场主体的利益分配及后续区域市场运营的持续性。本文基于南方区域统一电力现货市场,研究跨省中长期合约主体在不承担与承担跨省中长期合约阻塞费用两种模式下现货跨省阻塞不平衡资金计算、分摊方法,分析跨省阻塞不平衡资金为负情况产生的原因,并提出应对措施。进而,构建算例验证本文所提跨省阻塞不平衡资金计算方法的正确性。基于此,市场初期跨省中长期合约主体不应承担跨省中长期合约阻塞费用,后期应逐步回归跨省中长期交易的金融属性,并令其承担相关阻塞费用,同时设计金融输电权交易品种,完善金融风险对冲工具。

The construction of regional electricity spot markets is an important part of building a unified national electricity market.In the southern region,a unified and balanced centralized regional electricity spot market has been established,and trial operation of power adjustment settlement has been carried out.The rationality of the calculation and guidance of inter provincial blocking of unbalanced funds is related to the distribution of interests among market entities in provinces and the sustainability of subsequent regional market operations.This article is based on the unified electricity spot market in the southern region,and studies the calculation and allocation methods of unbalanced funds for cross provincial blocking of spot contracts under two modes:non assumption and assumption of blocking costs for cross provincial medium and long-term contracts.It analyzes the reasons for the negative situation of unbalanced funds in cross provincial blocking and proposes countermeasures.Furthermore,a numerical example is constructed to verify the correctness of the proposed method for calculating unbalanced funds in cross provincial blocking.Based on this,in the initial stage of the market,cross provincial medium and long-term contract entities should not bear the blocking costs of cross provincial medium and long-term contracts.In the later stage,they should gradually return to the financial attributes of cross provincial medium and long-term transactions and make them bear the relevant blocking costs.At the same time,design financial transmission rights trading varieties and improve financial risk hedging tools.
