The invention relates to the technical field of
electric power, in particular to a multi-
energy system combined installation
planning method based on global benefit maximization. The method comprisesthe steps of constructing a pumped storage
power station joint planning model; solving the planning model by using a two-layer optimization method; and obtaining a
system planning result by using a Cplex optimization
software. According to the method, the
wind power absorption capacity of the northern areas can be improved, the disturbance rejection capacity and the
wind power absorption capacityof the
system are improved on the premise of considering the company benefits and
social benefits, and the peak regulation capacity of the
system after
wind power grid connection is improved. The method also consider the factors, such as the fluctuation of the system load and the wind power, a power supply structure, the
power grid peak shaving capacity, the influence of the wind power on the peakshaving capacity after the power wind accesses in a
power grid, etc., comprehensively, and can quantitatively evaluate the limitation degree of the
power grid peak shaving on the wind power acceptance capacity. The method is helpful for meeting the energy-saving and environment-friendly,
clean energy admission and other political demands in China, and can be used for improving the power grid power supply structure in China, reducing the power generation cost and improving the safe and stable operation capability of the power grid.
