摘要： A combined electrical power plant is provided to supply power to a grid and a method to operate such a combined electrical power plant comprising a thermal power generation facility and an energy storage facility with a suitable energy storage capacity being able to supply additional electrical power to the grid and to receive and store electrical power from the thermal power generation facility or from the grid. Both facilities are electrically coupled to providing a combined power output to the grid and further comprise a plant controller to process the demand signal and to generate at least a first control signal and a second control signal from the demand signal, where the first control signal is a smoothened function of time of the demand signal resulting from a smoothening process executed by the plant controller taking into account operational characteristics of the thermal power generation facility.

摘要： Provided is a frequency regulation method for regulating a frequency of a power system so that the frequency approximates to a rated frequency, the method including: measuring the frequency; obtaining an SOC (state of charge) of a storage battery; determining a base-point of power to be charged in or discharged from the storage battery when the measured frequency is equal to a predetermined rated frequency; determining a control variable changed from the base-point by an amount corresponding to a frequency deviation that is a difference between the predetermined rated frequency and the measured frequency; and charging or discharging the storage battery based on the control variable, wherein in the determining a base-point, a third rate of change is smaller than a first rate of change and a second rate of change that are average rates of change in the base-point with respect to the SOC when the SOC is within a first range and a second range, respectively.

摘要： A vehicle-to-grid system connected to a power grid includes a first vehicle group of one or more vehicles connected to the power grid, a second vehicle group of one or more vehicles connected to the power grid, and a vehicle-to-grid controller. The vehicle-to-grid controller causes each vehicle from the second vehicle group to supply electrical power to the power grid at a nominal frequency and at an adjusted amplitude, and causes each vehicle from the first vehicle group to supply electrical power to the power grid at an adjusted frequency that is different than the nominal frequency and at a nominal amplitude that is different than the adjusted amplitude.
