Environment models of varies locations within the photovoltaic power plant are obtained. A photovoltaic display model is established by establishing a photovoltaic cell model, combining the photovoltaic cell model with the environment models, determining a combination of the environmental data on photovoltaic panels and the photovoltaic cell model, and determining a quantitative relationship between a photovoltaic cell power generation state and photovoltaic environment. An inverter model is obtained by modeling inverters connected to photovoltaic cells. A grid-side model is obtained. An electrical energy and voltage forecast model is constructed by integrated the photovoltaic display model, the inverter model, and the grid-side model.

Abstract: A method of simulating wind field of extreme arid region based on WRF includes following steps. A mode parameter optimization scheme for wind energy simulation is selected, wherein the mode parameter optimization scheme is selected by selecting a group of mode parameter optimization schemes of different ground floors, land process, and planet boundary layers having great influence on simulation of the boundary layer of wind field, and comparing the mode parameter optimization schemes. A wind energy simulation of the extreme arid region is performed during a preset length of time using the selected mode parameter optimization scheme. Simulation configuration of the wind field for the extreme arid region is obtained through results of the wind energy simulation.

Abstract: A method of controlling inertia response of variable-speed wind turbine generator includes following steps. A maximum wind power of the wind turbine is gotten through a wind speed ?w and a rotation speed ?r at the hub of the wind turbine based on a maximum wind power tracking control strategy. The maximum wind power is set as an active power control reference value P0 of the wind turbine. A grid frequency f is obtained via a frequency measurement equipment. An additional active power control reference value ?P of the wind turbine is generated based on the grid frequency f via an additional control block, and the additional active power control reference value ?P is added on the active power control reference value P0, wherein a total of active power control reference value of the wind turbine is P0+?P.
