新型电力系统下省间−省内2级市场交易模式设计及出清优化
摘要：为实现“碳达峰，碳中和”目标，习近平总书记提出构建以新能源为主体的电力系统。建立面向低碳能源转型的新型电力系统市场交易模式是实现“双碳”目标的重要途径之一。为此，提出省间−省内2级市场交易模式及出清优化模型。首先，分析新型电力系统下高比例清洁能源接入、高比例跨区电力输送以及高比例灵活资源调节的特征并描述其市场交易框架。其次，设计以新能源为主体的省内市场交易，包括年度双边协商/集中竞价交易、月度双边协商/集中竞价交易、月内(多日)交易以及辅助服务交易；设计省间交易模式，包括年度/月度跨省跨区交易、省间购电交易、清洁能源外送交易以及省间调峰辅助服务交易。在满足电力供需平衡的基础上，构建以省内清洁能源消纳量最大为目标的日前市场出清模型和以总成本最小为目标的日内市场出清模型。最后，以某省新型电力系统为例，模拟典型场景下的日前市场交易和日内市场交易，结果表明所提市场交易模式有效地促进了清洁能源消纳，减缓了弃风弃光、拉闸限电等现象的发生，推动了“双碳”目标的实现。
Abstract:In order to achieve the goal of “carbon peaking and carbon neutrality”, General Secretary Xi Jinping proposed to build a power system with new energy as the main body. It is one of the important ways to realize the goal of “double carbon” to establish a new power system market trading mode for low-carbon energy transition. Therefore, a two-level inter-provincial-intra-provincial market transaction model and a clearing optimization model were proposed. First, the paper analyzed the characteristics of high proportion of clean energy access, high proportion of cross-regional power transmission and high proportion of flexible resource regulation under the new power system and described its market trading framework. Secondly, the provincial market transaction with new energy as the main body was designed, including annual bilateral negotiation/centralized bidding transaction, monthly bilateral negotiation/centralized bidding transaction, monthly (multi-day) transaction and auxiliary service transaction. Inter-provincial transaction mode was designed, including annual/monthly inter-provincial and inter-regional transaction, inter-provincial electricity purchase transaction, clean energy delivery transaction and inter-provincial peak regulation auxiliary service transaction. On the basis that the balance between supply and demand of electricity is satisfied, the day-ahead market clearing model aiming at the maximum consumption of clean energy in the province and the day-ahead market clearing model aiming at the minimum total cost were constructed. Finally, a new power system in a province was taken as an example to simulate day-ahead and day-day market trading under typical scenarios. The results show that the proposed market trading mode effectively promotes the consumption of clean energy, slows down the occurrence of wind and light abandonment, power rationing and other phenomena, and promotes the realization of the " double carbon " goal.
