| 摘 要： | 根据区域电网的特点,研究售电公司、电网公司和用电客户之间的电量交易。考虑到交易过程中的供需差异等因素,建立了基于输电费用优化的非合作博弈售电策略模型。以区域电网为例,分析各利益主体在非合作博弈模型下的纳什均衡售电策略。算例分析结果表明,非合作博弈售电策略模型不仅可为售电公司提供竞价参考、平衡可再生能源和传统火电之间的利益,同时也可降低区域电能供需不平衡概率,保障电力市场安全运行。

| Abstract: | According to the characteristics of regional power grid, the electricity transaction among electricity distribution company, power grid company and electricity customer is studied. Considering the differences between supply and demand during the transaction process, a non cooperative game selling strategy model based on transmission cost optimization is established. Taking regional power grid as an example, the Nash equilibrium power sales strategy of various stakeholders is analyzed under the non?coopera?tivegame model. Results show that the model not only provides bidding reference for the sales company and balances the benefits between renewable energy and traditional thermal power, but also reduces the imbalance probability of regional power supply and demand and ensures the safe operation of the electricity market. |
