摘要:

针对电网运行面临的多重不确定风险,文中从风险发展时序特征和电网运行调控模式的角度分析了风险协调控制的必要性。基于风险协调控制的观点,提出了一种计及中短期、日前、实时和事故后4个阶段的电网运行全过程风险协调控制体系,详细阐述了各阶段的风险优化模型、控制措施和协调策略,提出了五层式软件架构方案,讨论了支撑系统应用的关键技术。最后介绍了全过程风险协调控制体系在浙江电网的初步应用情况。理论分析和工程实践结果表明,所提出的全过程风险协调控制方法能够适应现有的“三公”调度体制,统筹协调各阶段的调度控制决策,实现电网运行风险的逐级跟踪与滚动调控。

Abstract:

For the multiple uncertain risk factors faced by the operation of power grid, this paper analyzes the necessity of risk coordination control from the perspective of the sequential characteristic of risk development and the dispatch mode of power grid. Based on the view point of risk coordination control, a system of risk coordination control for the whole operation process of power grid including medium and short-term, day-ahead, real-time and post-contingency is proposed. The risk optimization models, control measures and coordination strategies at each stage are elaborated in detail. The solution based on a five-tier software framework is proposed and key technologies supporting the system application are discussed. Finally, the preliminary implementation of the whole process risk coordination control system in the Zhejiang Power Grid of China is introduced. The results of theoretical analysis and engineering practice show that the proposed system and framework can adapt to the “open, fair and just” power dispatch mode, coordinate the risk control decisions at different stages and realize the step-by-step tracking and rolling control for the operation risk of power grid.
