【摘要】：电网调度运行对掌握未来状态安全变化的迫切性越来越高,针对此问题,结合当前智能电网调度控制系统及其动态安全评估技术的发展,提出了运行方式安排的大电网在线趋势分析技术。该技术基于电网当前运行方式和在线稳定分析结论,利用调度操作调整、调度计划、新能源预报和负荷预测数据,形成电网未来时刻的预估潮流,在短周期内快速评估其安全状况及变化趋势,并给出辅助决策控制策略。该技术已在华中、黑龙江电网得到了应用,为复杂电网调度运行控制提供了预防预控的技术支撑手段,促进了电网控制从经验型向智能型的转化。
[Abstract]:Power grid dispatching is becoming more and more urgent to grasp the future state security changes. In view of this problem, combined with the development of smart grid dispatching control system and its dynamic security evaluation technology, Based on the current operation mode and the conclusions of on-line stability analysis, the technology uses dispatching operation adjustment, scheduling plan, new energy forecasting and load forecasting data. To form the estimated power flow at the future time of the power network, to evaluate the security situation and the change trend in a short period of time, and to give the auxiliary decision control strategy. The technology has been applied in central China and Heilongjiang power grid. It provides the technical support for preventing and controlling the complex power grid dispatching operation control, and promotes the transformation of the power network control from the experiential type to the intelligent one.
