| 摘要: |
| 结合抽水蓄能电站水库水头与储能之间的关联关系，以及抽水蓄能机组出力的最高、最低限制，确定了机组最优的发电出力投标；在能够预测批发电力市场出清价格的基础上，构建了日前市场、双边合约市场以及辅助服务市场组合模式下的机组参与市场竞价的约束条件；同时引入了市场风险因素，建立了抽水蓄能机组在组合市场模式下的竞价决策模型；引入混沌变量对蚁群算法局部搜索部分进行了改进，并对决策模型进行求解。算例分析表明，在电力市场环境下，抽水蓄能电站通过合理安排发电计划和竞价决策能够获得更大的经济效益。 |

| Abstract: |
| The optimal unit power output of pumped storage plant for bidding is determined according to the relationship between its water head and energy storage，as well as the maximum and minimum output limits. Based on the assumption that the market clearing price can be forecast，the constraints of the unit participating in power market competition are constructed for the combined mode of day-ahead market，bilateral contract market and ancillary service market. The bidding model of pumped storage unit in the combined market mode is built with the consideration of market risk factors. A chaotic variable is introduced into the ant colony algorithm to improve its local search for solving the bidding model. Case analysis shows that，the pumped storage plant with proper generation schedule and bidding strategy can obtain greater economic benefits in electric power market. |
