多能源参与的电力主辅市场联合优化模型

我国新一轮电力体制改革稳步推进,成效显著。辅助服务市场与现货市场的协调运行方式已成为下一阶段现货市场试点建设的关键问题之一。风电、光伏等多种类型的发电资源共同参与电力市场竞争,已成为我国电力市场发展的必然趋势。为此,提出了多能源参与的电力现货与辅助服务市场的联合运行方式,构建了现货与辅助服务市场的联合优化出清模型,包含了常规火电机组、水电机组、风电、光伏等新能源机组共同参与市场竞争,考虑了机组运行与电网运行的各类安全约束条件。在此基础上,构建了算例验证所提出的联合优化模型的正确性与有效性,分析了主辅市场联合运行的出清结果与效益。

Optimization model for combined electricity spot and ancillary service markets considering variable generation resources

The new round of deregulation and reform of powerindustry in China are push forward steadily and achieve remarkable success. The combined operation of spot markets and ancillary services markets will be the key problem of electricity markets construction in the next step. Variable generation resources jointly competing in the electricity markets will be the inevitable development trend of China. Firstly, a combined operation mode of spot and ancillary services markets is processing by considering vari able generation resources. The optimization clearing model of energy and ancillary services markets are also constructed. The thermalunits, hydro units, wind units and solar units are all considered in the model and their operation constraints should be satisfied. Finally, the numerical examples are performed to validate the effectiveness of the proposed model and to analyze the clearing results and benefits of the combined operation mode.
