Design and Application of Intelligent Power Control System for Integration of Renewable Energy
摘要
Abstract
Several existing problems in current power control of renewable energy are analyzed and the functional design and strategy of the intelligent control system for grid-connected power of renewable energy is introduced.The online sensitivity calculation method of the renewable energy station is proposed.Firstly, equivalent device in the state estimation system is confirmed according to grid-connected network of renewable energy power station.Based on real-time operation mode of the grid, the sensitivity of the equivalent device is calculated and then converted into the sensitivity of renewable energy station.The station/unit participating in the section control and the quantity of adjusted power is determined, and the problem of windcoal coordinating control under the complex network structure is solved.When the renewable energy participates in peak regulation by tracking the negative spare capacity considering the regulation rate of thermal power unit and the area control error, the executed instructions would be adjusted in time once an exception occurs to ensure that automatic generation control (AGC) assessment indicators could meet the requirements.According to the power generation capacity, installed capacity and grid receiving space of the integrated renewable energy power station, the control sequence is determined and updated dynamically.The strategy can realize resource priority and fairness control among renewable energy stations and ensure the maximized consumption of renewable energy power.The operation result in Shanxi power grid shows that the intelligent control system can guarantee effectiveness of ensuring safe and stable operation of power grids, improving new energy consumption and promoting fair dispatch of new energy power stations.关键词
