智能电网关键词（Smart grid keyword） 1, distributed generation: The combination of the large grid and the distributed grid has been recognized by many energy and power experts in the world as a way to save money The main way to reduce energy consumption and improve the reliability and flexibility of the power system is the 21 actual power worker Development direction of the industry. Distributed generation refers to the distribution of the load near the load through a small size even kW to tens of mw Electrical facilities, economy, reliable power generation. Is not a whole new concept, the early small thermal power, small hair Electricity is also distributed power generation, but because of technical and economic performance is not good, gradually eliminated. Emerging distributed generation technologies include fuel cell generation technology, micro gas turbine power generation technology, and Photovoltaic cell generation technology. The impact of distributed generators on the modern power industry: the impact of a on power generation and transmission systems lies in The demand for new centralized large power plants and long distance power lines reduces the impact of B on the distribution network system C, the impact on the entire power industry 2 、 reactive compensation: Reactive power compensation is to improve the utilization and efficiency of power, ensure the quality of power, the most extreme An unnecessary loss of electrical energy. Reactive power compensation improves AC power by modulating reactive power Performance of electrical system. The concept of reactive power compensation involves all aspects of system and application, especially Power quality related problems, because most of the power quality problems can be done by reactive power Controlled or relieved or settled completely. The power factor in the grid is not high and can cause many undesirable effects. Work The rate factor is not high enough to make the capacity of the power generation equipment not fu
