摘要：
In order to promote the optimal allocation function of energy resources，China has gradually formed the two-level electricity market of“unified market，two-level operation”. In the early stage of the construction of two-level electricity market，it is an urgent issue to be studied that the plan for new energy stations participate inter-provincial electricity spot trading lacks guidance. First of all，an in-depth study of the current mechanism of inter-provincial and intra-provincial electricity market is conducted and its operating framework is discussed. Then considering the multi-spatial and multi-time coupling characteristics of inter-provincial power spot trading and auxiliary service market，a two-layer optimal model for power sales decision-making of new energy stations in two-level electricity market is constructed，and the lower-layer model is transformed based on the conditional value-at-risk，which realizes the uncertainty control of the new energy stations’output. Finally，relying on the actual data of a project in some province of Northeast China，an example analysis is carried out. The results show that the model can improve the market revenues of new energy stations under the two-level electricity market environment. © 2023 Electric Power Automation Equipment Press.
