摘要

在“碳达峰·碳中和”的目标驱动下，受新能源地理分布与随机性影响，以跨区域交易为媒介的区域间电能与灵活性互济重要性凸显。目前，中国正处于构建全国统一电力市场体系的关键阶段，需要有效的市场机制来管理省间电力现货交易。基于上述背景，设计了一种不依赖于跨区域投标者的省间电力现货交易方法。首先，提出了基于报价区的市场出清模型，采用分区边际定价的方法计算每个报价区的结算价格；然后，基于等效双边配对方法

按潮流贡献计算得到各区域间交易所需承担的输电费用；最后，采用算例验证了所提方法的有效性。与已有方法相比，所提方法在不依赖于跨区域投标者的前提下完成了跨区跨省电力交易，充分利用了输电线路容量，且市场出清过程中保护了各区域内部网架信息隐私。

Abstract

Driven by the goal of “carbon emission peak and carbon neutrality” and affected by the geographical distribution and randomness of renewable energy

the importance of mutual support between regional power and flexibility using cross-regional trading as a medium is highlighted. At present

China is in the critical stage of building a unified national electricity market system

and an effective market mechanism is needed to manage large-scale inter-provincial electricity spot trading. Based on the above background

an inter-provincial electricity spot trading approach which does not depend on cross-regional bidders is designed. First

a market clearing model based on bidding zones is proposed and the zonal marginal pricing method is used to calculate the settlement price for each zone. Then

transmission tariffs for each transaction between regions are calculated according to power flow contributions based on the equivalent bilateral matching method. Finally

numerical examples verify the effectiveness of the proposed method. Compared with existing methods

the proposed method accomplishes inter-provincial electricity trading without relying on cross-regional bidders. It utilizes the capacity of transmission lines efficiently and protects the privacy of internal network information in each area during the market clearing process.
