Abstract

The invention discloses a multi-energy system collaborative scheduling method and device based on electric car access, and relates to the field of smart power grids. The method includes the steps of dividing electric car clusters according to statistical data of the time of the electric car accessing to a power grid and the time leaving the power grid, obtaining a current scheduling model of electric car clustering according to probability density and charging demand information of each electric car cluster accessing to and leaving the power grid in a corresponding period to build a multi-energy system cooperative scheduling model, using a multi-group balanced collaborative search algorithm to obtain energy supply cost and an optimal charge and discharge strategy with the lowest pollutantemission, and charging and discharging each electric car cluster. The method and device can reduce the energy supply cost, reduce the pollutants, improve the operation status of the multi-energy system, and prevent unnecessary faults from occurring; meanwhile, in a process of optimizing a charging and discharging mode, energy storage scheduling in the smart power grid is also optimized to suppressthe uncertainty of the smart power grid and reduce the construction cost of the smart power grid.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to a multi-energy system coordinated scheduling method and device based on electric vehicle access. Background technique [0002] With the development of multi-energy systems and the popularization of electric vehicles, how to effectively coordinate the dispatch of multi-energy systems and electric vehicles is a problem that must be faced in the future energy Internet to achieve "source-network-load" coordination, especially After the power-to-gas equipment and gas storage equipment are added to the energy center, the degree of coupling between the power grid and the gas grid is more profound. [0003] After the traditional power grid dispatching mode is connected to the electric vehicle, due to the increase of the coupling constraint of the time period, it is equivalent to expanding the node scale several times, which will inevitably introduce a large number of variables, greatly increas...
