摘要:
      将各种安全稳定问题按重要和复杂程度进行排序,获得各问题的计算队列,确保优先给出对电网安全稳定运行影响程度高的安全稳定问题对应的辅助决策;采用安全稳定性指标对候选控制措施的灵敏度或参与因子信息作为安全稳定约束,避免各类辅助决策功能给出相互矛盾的控制措施;各辅助决策功能通过计及队列中之前的辅助决策措施,避免同时调整同一类控制措施;针对不同类型的控制措施,通过设置优先级顺序,计算各控制措施的综合性能指标,根据设置的门槛值筛选有效控制措施并同时调整性能代价相近的措施,确保辅助决策给出的控制策略符合调度运行人员的操作习惯。通过对华北电网的案例分析验证了该方法的有效性和实用性。
Abstract:
      To ensure that auxiliary decision-making on the security and stability problem with greater influence on the power system is given priority, the calculation sequence of various security and stability problems is obtained based on the sorting results according to importance and complexity. To prevent giving conflicting control measures of all kinds of auxiliary decision-making functions, the sensitivity or participation factor of the candidate control measures for the security and stability index is taken as security and stability constraints in the coordination and optimization process. To avoid adjusting the same class control measures at the same time the auxiliary decision-making is being searched, previous auxiliary decision-making results in the queue are taken into account. To ensure that the control strategies of auxiliary decision-making are in conformity with the operation habits of dispatchers, comprehensive control performance indicators of different kinds of control measures are calculated in conjunction with priority order setting. Effective control measures are screened by setting the threshold value of control performance indicators, and the measures with similar control performance indicators are adjusted. The effectiveness and practicality of the method have been verified by cases in point in North China Power Grid.
