摘要
首先建立了一种完全竞争电力市场环境下的水电机组线性优化调度模型,既考虑了电厂运行的技术和物理约束,也考虑了用水的持续综合效益。然后提出了一种新的水价值估计方法,可用于指导电厂确定自身的报价是否合适,从而提高中标机会。针对调度模型的结构特点采用变量有界的单纯形算法对其进行求解,使整个计算过程简单快速。采用上述方法对某实际水电厂进行了仿真计算,结果表明本文推荐的模型中电价对资源的利用具有引导作用,当计及蓄能效益时,虽然计划期内的发电效益下降,但总体效益增加,这说明该模型是可行有效的。
At first a practical linear optimal dispatching model under complete competitive electricity market is established in which the technical and physical constraints in power station operation as well as the sustained comprehensive benefit of water utilization are considered. Then a new water value evaluation method is proposed which can be used to guide the power station confirming whether its own bidding price is appropriate, thus the chance of acceptance of the bid may be improved. According to the structural feature of dispatching model the variable bounded simplex algorithm is adopted to solve the model, it makes the calculation simple and fast. Simulation results of an actual hydropower station show that in the established model the electricity price plays leading role in the utilization of resources. When the revenue from energy storage is taken into account, the revenue from power generation within the planning period decreases, but the total revenue increases, so it is shown that proposed model is effective and feasible.
