中文摘要：

为了应对日益严峻的能源与环境形势,中国颁布并实施了电网节能发电调度办法。由于该办法仅仅提供了基本的调度原则,广东电网在节能发电调度的推行过程中,缺少能满足政策的节能发电调度模型与算法。为解决这一实际问题,在分析现有节能发电调度方案不足的基础上,提出了考虑节能发电调度规则的混合整数线性规划机组组合与发电计划模型,以实现广东电网的节能发电调度。由于广东电网的抽水蓄能装机容量比重较高,在模型中考虑了抽水蓄能的作用。所提模型的有效性在IEEE10机39节点系统上得到验证。将该模型用于广东实际电网,分别给出了以节煤和降低购电成本为目标的广东电网节能发电调度模式下的调度策略及分析。在此基础上,探讨广东电网抽水蓄能机组在不同调度模式下的一般调度原则。

英文摘要：

To meet the requirements of energy saving and environment protection, the energy-saving generation dispatching policy （ESGDP） has been promulgated and implemented in power girds of China. The core of ESGDP is to establish a dispatching sequence for each of units, and then schedule and dispatch them in order. However, the ESGDP only provides general dispatching principles without comprehensive model and algorithm for energy-saving dispatching, which discourages the implementation of ESGDP in Guangdong power grid at large. To solve this engineering problem, this paper proposes a mix integer linear programming （MILP） based unit commitment （UC） and generation scheduling model considering the ESGDP. In view of a large capacity of pumped storage hydro in Guangdong power grid, the effects of pumped storage plants are further taken into account in the energy-saving dispatching model. Effectiveness of the proposed model is verified on the IEEE-39bus power system. Using the real data of Guangdong power grid, the energy-saving dispatching strategies are determined and analyzed for different dispatching modes for minimizing the fuel cost and the electricity purchasing cost, respectively. Furthermore, some general principles are suggested for using pumped storage plants under different modes of energy-saving dispatching in Guangdong power grid.
