Refined Control Performance Standard Considering Capacities of New Energy Sources and Conventional Power Sources of Control Area

At present, the installed capacity of new energy in China's regional power grids is gradually rising, the power structure has become complex, and the intermittency and volatility of new energy output bring great challenges to the grid frequency. Automatic generation control, as an important means of secondary frequency regulation, plays an irreplaceable role in maintaining system frequency security, while CPS (control performance standard) standard, as an important criterion for restraining the behavior of the units in each control area, makes great contributions to the fair and impartial assessment of the behavior of the units in each control area and the maintenance of system frequency security. However, due to its own defects, the original CPS standard can not be better adapted to China's power grid, which has a complex power supply structure. In order to better maintain the frequency security of the power system, assess the control areas in a fair and impartial manner, and promote the mutual support of power among the areas, this paper improves the original CPS standard. Firstly, the connotation of the original CPS standard is analyzed, the deficiencies of the original CPS standard are pointed out, and improvements are made for the actual situation of the power grid. The new method proposed in this paper has a solid theoretical foundation, taking into full consideration the different capacities of new energy sources and conventional power sources in each area. The method proposed in this paper has been applied in a power grid and achieved good results.
