| 摘要 |
The present disclosure relates to a method for controlling plant active power output Pplant ramp rate of a power plant 1 to a PCC with a power grid. The method comprises obtaining information about a current RES active power output PRES of a Renewable Energy Source (RES) 2 comprised in the power plant. The method also comprises forecasting future RES active power output, during a predefined future time period. The method also comprises, based on the obtained current RES active power output information and on the forecasted RES active power output, determining whether an expected ramp rate of the RES active power output during said predefined time period exceeds a predefined maximum ramp rate limit of a plant active power output. The method also comprises, based on said determining, selecting a first control method which is based on the forecasted future RES active power output if it is determined that the expected ramp rate exceeds the predefined maximum ramp rate limit, or selecting a second control method, different from the first control method, if it is determined that the expected ramp rate does not exceed the predefined maximum ramp rate limit. The method also comprises using the selected first or second control method to generate an ESS control signal for controlling the ESS active power output PESS such that the plant active power output ramp rate is kept below the predefined maximum ramp rate limit during the predefined time period. |
