Chapter 1 Summary(第一章 概述)Ⅰ. Electric power system dispatch automation task(电力系统调度自动化任务) The five utilities of national grid（in china）： （国家电网公司下属的五大电网 ） Northeast Grid；North China Grid；Central China Grid；Northwest Grid；South Grid.（ 东北电网；华北电网；华东电网；华中电网；西北电网；南方电网。 ） Northeast Grid, North China Grid, East China Grid, Central China Grid, Northwest Grid, South Grid have been formed a national network.(东北电网、华北电网、华东电网、 华中电网、西北电网、南方电网Southern Grid已实现互联，形成全国统一电网。) The advantage of economic and stable about the modern electric power system：（现代电力系统在经济和稳定方面优势： ） 1. Different resource in different places can complete each other and improve the economic operation. （各地区不同特性的资源可以互相补充，提高运行的经济性。 ） 2. Use of time difference in different places can reduce the gap between peak and trough，reduce the total installed capacity. （利用各地区的时间差，可以平抑峰谷差，减少总装机容量） Easily occur a chain of large scale malfunctions, hard to analyze the safety ,stability problem prominent, and a higher demand for dispatch. （发生大规模连锁故障风险增大，安全分析更加困难，稳定问题突出，给调度提出了更高的要求。） How to coordinate between the various subsystems, between the hydroelectricity and coal-fired power , how to consider global and local interests, is a problem of challenge. (各子系统之间如何协调，全局和局部利益如何统筹考虑，水火电如何配合等都具有挑战性。) 5. Power system scheduling tasks(电力系统调度任务) 1）Electricity load forecasting (预测用电负荷) According to the changes of load history, weather forecast, analysis of electricity production and people’s pattern of life, the next 24 or 48 hours for full system load forecasting, preparing expected load curve, with a generating capacity to adapt better. ( 根据负荷变化的历史记录、天气预报、分析用电生产情况和人民生活规律，对未来24小时或48小时进行全系统负荷预测,编制预计负荷曲线,配备好相适应的发电容量) 2）Formulate the generating, operation mode and operation plan： (制订发电任务、运行方式和运行计划) ① According the load curve forecasting, economic dispatch principle to make a reasonable plan and arrangement of water and fuel distribute the task of each power plant (inclu
