Optimization for Primary Frequency Regulation Performance of Large Pumped Storage Unit

For raising the capacity of primary frequency regulation of pumped storage unit, improving operation performance and enhancing electric power quality, the test of primary frequency regulation is implemented by combining mathematical modeling simulation and field running test. And then the Cohen-Coon method is used to optimize the operation parameters for studying the response characteristics of units in primary frequency regulation with different parameters. The test results show that the primary frequency regulation performance and response characteristics of the units are greatly improved after optimizing parameters; response speed of the system is obvious quickly and the performance index is more optimal.
