摘要

为了适应中国电力市场化改革不断深化的进程,本文提出了梯级水电站现货交易结果的模拟与演绎技术。结合中国四川省的市场模式、交易规则与调度、生产模式,从四个角度对交易结果进行了模拟和推导。基于梯级水电站复杂的水电连接和多维非线性约束,建立了梯级水电站现货市场交易的仿真推导模型,设计了具有指定输出的分块多序贯算法进行计算。选取西南大渡河流域8个CHSs某一天的现货交易结果对该方法进行验证。计算结果表明,本文提出的方法可以有效地识别现货交易中的竞价风险。为CHSs现货交易竞价申报提供辅助决策支持,满足当前电力市场环境下市场化生产的生产方式。

Simulation and Deduction Technology for the Result of Spot Transactions for Cascade Hydropower Stations
In order to adapt to the process of constantly deepening China’s electricity market reform, this paper presents a simulation and deduction technology for the result of spot transactions for cascade hydropower stations. Combining with the market modes, transactions rules and scheduling, and production modes in Sichuan, China, the transaction results were simulated and deduced from four perspectives. Based on complex hydraulic and electric connections of cascade hydropower stations (CHSs), and multi-dimensional non-linear constraints, a simulation and deduction model for spot market transaction of CHSs was established and the block multi-sequential algorithm with specified outputs was designed for calculation. The results of spot transactions of eight CHSs in the Dadu River Basin in southwestern China on a certain day were selected for verification of this method. The calculated results show that the method proposed in this paper can identify the bidding risk in a spot transaction. It provides an assistant decision support for the declaration of the bidding in spot transactions of CHSs and satisfies the mode of production of market-based production in the prevailing electricity market environment.
