P2X技术进展及其参与电力系统运行优化模拟研究

电转气（power to x，P2X）是电能向热、冷、气等能源形式转换的前沿技术理念。从P2X的基本概念出发，对P2X技术体系进行了综述，评价了各类主要技术的经济性与发展潜力，提出了电力系统视角下P2X的角色与价值。进而构建了考虑P2X灵活性负荷的电力系统运行模拟优化模型，并以华北地区远景目标年为场景，对电采暖、电制氢负荷优化运行进行了模拟研究，结果表明P2X负荷通过参与电力系统优化运行，对降低新能源弃能率具有重要作用。

P2X Technology Progress and Simulation Studies on Its Participation in Power System Operation Optimization

As a cutting-edge technological concept, P2X represents the conversion of electrical energy to heat, cold, gas and other forms of energy. Based on the basic concept of P2X, this paper reviews the P2X technology system, evaluates the economics and development potential of various major technologies, and proposes the role and value of P2X from the perspective of power systems. Furthermore, a simulation model of power system operation optimization considering P2X flexible load is constructed. Taking the long-term target year of North China region as the case scenario, a numerical study is carried out on the optimal operation of electrical heating and hydrogen production load. The analysis result demonstrates significant impacts of P2X flexible load on the curtailment rate of new energy generation.
