考虑峰谷分时电价策略的源荷协调多目标发电调度模型

Multi-objective generation scheduling model of source and load considering the strategy of TOU price

针对新形势下电力调度的发展需求,提出了一种考虑峰谷分时电价策略的源荷协调多目标发电调度模型。首先,探讨了峰谷分时电价对电源及负荷侧的影响机理,从用户电费支出及用电方式两个角度给出了负荷参与峰谷分时电价的满意度指标。其次,以峰谷分时电价为杠杆,将电源侧的发电成本问题以及负荷侧的用电问题进行有效关联,从源荷两侧建立一个多目标发电调度模型,并进一步给出相应的求解算法。该方法能从电源和负荷两侧最大限度地挖掘发电调度的效益,所得的方案也符合各方的利益需求。最后,通过一个省级电网的算例说明了所提方法的有效性。

Responding to the speedy development of generation scheduling of modern power grid, a novel multi-objective generation scheduling model of source and load considering the time-of-use price is proposed. First, the effects of time-of-use price to the source and load are analyzed, and the satisfaction indexes of customers are given from the costs and habit of customers. Then a multi-objective generation scheduling model is presented by considering both of the generation cost and the customer satisfaction based on time-of-use price. The solving algorithm is also given. In this way, the benefit of generation scheduling is maximized from both sides of source and load, the interests of source and load are also considered well. Finally, the proposed method is tested in a provincial grid, and the effectiveness is demonstrated fully.
