考虑碳排放约束的新能源与调峰资源优化配置方法

Research on the Optimal Configuration Method of New Energy and Flexible Regulation Resources Considering Carbon Emission Constraint

“双碳”目标下,随着新能源并网装机规模加速增长,系统调峰需求快速增长,新能源与系统调峰资源协同优化发展成为高质量构建新型电力系统的重点之一。本文引入碳排放约束,构建了综合考虑新增机组投资与系统运行成本的新能源与调峰资源优化配置模型,针对不同新能源利用率目标,设置多个发展场景,研究了不同场景下的电力系统运行经济性。考虑未来以省(市)为单位进行碳减排评估与考核,以中部地区的省级电网为研究算例,验证了所提模型方法的有效性。

In the goal of the"Dual Carbon",with the rapid increase of the installed capacity of new energy,the demand for system regulation resources is also growing fast.Hence the coordination and optimization of the new energy and regulation resources is getting more attentions in building a new-type power system with high quality.This paper constructs an optimization model for new energy and regulation resources development with the objective of minimizing investment cost of additional units and operating cost of the system subject to carbon emission constraint and other constraints.Multiple development scenarios are set up with respect to different utilization rates of the new energy,and the operational economics of power system under each scenario are studied.Considering the carbon emission reduction target will be established and assessed for each province individually in the future,a provincial power grid in central China is taken as an example to verify the effectiveness of the proposed model,and research results and conclusions are provided at the end of paper.
