Capacity configuration and cost allocation method of multi-agent microgrid group joint energy storage system

Abstract

A multi-agent micro-grid group joint energy storage system capacity configuration and cost allocation method, comprising the following steps: taking the micro-grid group as a whole, establishing an energy storage capacity optimization configuration model to solve the optimal configuration capacity of energy storage, micro-grid group-year comprehensive The operating cost, the total net power curve of the microgrid group after considering the energy storage participating in the operation in the typical day of the four seasons; taking the independent operation of each microgrid as the object, modeling and solving the annual comprehensive operating cost of the independent construction and operation of the energy storage of each microgrid, and thus Calculate the additional income obtained by the joint construction of the energy storage system of the microgrid group; evaluate the contribution of each microgrid to the additional income from the two dimensions of energy contribution and net power waveform similarity, and thus obtain the cost allocation factor of each microgrid. In this way, the annual operating costs that need to be borne after the joint operation of each microgrid are calculated. This design can not only effectively quantify the capacity demand of the multi-agent microgrid for the joint energy storage system, but also allocate the cost of the energy storage system reasonably.

Description

technical field [0001] The invention relates to the field of optimal configuration of power system microgrids, in particular to a method for capacity configuration and cost allocation of a multi-subject microgrid group combined energy storage system. Background technique [0002] In order to achieve the "30·60" dual-carbon long-term goal, it is necessary to build a clean, low-carbon, safe and efficient energy system, deepen the reform of the power system, and build a new power system with new energy as the main body. With the rapid development of distributed clean energy, electric vehicles and user-side energy storage, the new power system undertakes the core functions of accessing multiple energy sources and supplying user energy consumption, while supporting multiple user interactions and distributed renewable energy access. The microgrid will become an important part of the end of the new power system. [0003] The grid-connected microgrid can achieve stable operation by...
