Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0022] figure 1 It is the micro-grid structure diagram of the charging-swapping-storage integrated power station. The charging-swap-storage integrated power station microgrid is composed of photovoltaic power generation, wind power generation, diesel engine, charging-swap-storage integrated power station and loads. Diesel engines and photovoltaic power generation are integrated into the microgrid through inverters and circuit breakers; integrated power stations are integrated into the microgrid through rectifiers and circuit breakers. In the present invention, an electric vehicle charging and swapping station and a storage battery energy storage station are combined to form a charging, discharging and storing integrated power station, which is incorporated into a microgrid....

Abstract

A cooperative game-based micro-grid optimal dispatching method for charging, exchanging and storing integrated power plants includes modeling photovoltaic power, wind power and electric vehicle powerexchange demands by using robust optimization considering electric vehicle power exchange demand and stochastic characteristics of photovoltaic and wind power generation; the optimal dispatching modelof upper micro-grid with minimum power supply cost being constructed; the life loss cost model and operation loss model of integrated power plant being established; constructing the optimization model of lower-level charging-replacing-storage integrated power station with the objective function of maximizing CSSIS profit; the optimal dispatching model of charge-exchange-storage integrated microgrid based on cooperative game being constructed. The model is solved by non-dominated sorting genetic algorithm with elite strategy (NSGAII) combined with solver CPLEX. The invention provides the theoretical basis and technical support for the construction of the charging and replacing infrastructure of the urban electric vehicle, and is beneficial to improving the economic benefits of the operation of the electric network, the micro-grid and the charging and replacing power station.

Description

technical field [0001] The invention relates to a micro-grid operation optimization technology, in particular to a cooperative game-based micro-grid optimization scheduling method for an integrated power station with charging, swapping and storage. Background technique [0002] As an important measure of energy saving and emission reduction, the development of electric vehicles has been paid more and more attention. Electric vehicles (EV) interact with the power system at charging facilities. EVs generate charging demand and then affect the temporal and spatial distribution of loads in the power system; at the same time, the power system provides charging services to EVs to meet the travel needs of EV users. Electric energy supply methods such as charging piles and charging and swapping stations provide diversified options for EV users to realize electric energy replenishment. For example, private EVs can obtain electric energy through slow charging piles, and can also perf...
