考虑备用共享的区域电力现货市场出清模型

在推进我国新一轮电力体制改革和建设全国统一电力市场的背景下,为了打破省间壁垒,缓解现行区域电力市场部分省份因备用容量不足和源荷逆向分布而存在的电力紧缺或“三弃”问题,引入备用共享机制和联络线协调优化的运行方式,构建了包括安全约束机组组合模型和安全约束经济调度模型在内的区域电力现货市场电能与备用联合出清模型。通过考虑备用共享的区域电力现货市场电能与备用联合出清,实现了电力资源在更大范围的优化配置,有效提高了系统运行的经济性和可靠性。以两个互联的IEEE 30节点系统模拟区域内两省间电力市场交易,验证了所提模型的正确性和有效性。

Clearing Model of Regional Electricity Spot Market Considering Reserve Sharing

Under the background of promoting our country’s new round of electric power system reform and building the national unified electricity market, in order to break down inter-provincial barriers and alleviate the power-shortage, abandoned water, wind curtailment and discarded light in some provinces of regional electricity market due to the lack of reserve capacity and the inverse distribution of energy and load, this paper introduces reserve sharing mechanism and coordinated optimization of tie-line, constructs a combined clearing model of energy and reserve for regional electricity spot market, including the security constraints of unit combination and security constraints of economic dispatch. Through combined clearing of energy and reserve for regional electricity spot market considering reserve sharing, the optimal allocation of power resources in a wider range is realized, and the economy and reliability of system operation are improved effectively. Two interconnected IEEE 30-node systems are used to simulate the electricity market transactions between two provinces in the region, and the correctness and effectiveness of the proposed model are verified.
