Description

Source-load storage resource coordination optimization and benefit distribution method Technical Field The invention relates to the field of source load storage resource optimization operation, in particular to a source load storage resource coordination optimization and benefit distribution method. Background With the wide access of distributed energy sources and the continuous development of the electric power market, the integrated project of source network charge storage becomes an important mode for improving the energy utilization efficiency, promoting the energy consumption and guaranteeing the stable operation of a power grid. But the current source network charge storage integrated project faces a plurality of problems when participating in electric power market transaction. On one hand, the traditional scheduling mode is difficult to realize collaborative optimization of each part of the source network load storage, so that the overall economic benefit of the project is low. For example, the power generation plan of the power generation resource may not match the load demand, the charging and discharging strategies of the energy storage resource are unreasonable, the transmission capacity of the power grid cannot be fully utilized, and the like. On the other hand, the benefit distribution in the project lacks fairness and transparency, and each participant has difficulty in accurately knowing the contribution and income conditions of the participant, so that benefit disputes are easily caused, and the long-term stable operation of the project is influenced. Therefore, a method for realizing collaborative scheduling optimization of source network charge storage integrated projects and ensuring reasonable benefit distribution of all participants is needed. Disclosure of Invention The invention aims to provide a source-load storage coordination optimization and benefit distribution method, which realizes benefit distribution publicity, scheduling optimization high efficiency and operation process transparency through mechanisms such as optimization decision, alliance coordination, weighted distribution, traceable ledger and the like. The method comprises the steps of establishing a centralized optimization scheduling model and a source load storage resource benefit distribution model. The centralized optimization scheduling model is used for maximizing the profit of the source load storage resource transaction. The source load storage resource benefit distribution model comprises a source load storage resource virtual internal transaction pool definition model and a comprehensive benefit distribution model. In the centralized optimization scheduling model, the maximization of the trading of the source load storage resources means that the source load storage resources are accessed to the electric market through an internal scheduling center, the scheduling center establishes a collaborative optimization model containing source, load and storage output power variables by collecting real-time operation parameters, cost parameters, response speed, reliability and controllability information of all the resources in the scheduling center, and the optimal scheduling scheme and the market trading plan are determined by taking the maximization of the overall profit into account and considering operation constraint conditions. In the source charge storage resource benefit distribution model, the source charge storage resource virtual internal transaction pool definition model refers to dividing internal transactions into four types, recording the internal energy and standby service transactions of each resource, and carrying out contribution degree pricing calculation of residual profits. Four classes of transactions refer to replacement real-time market transactions, transactions due to rescheduling spares, transactions due to daily market rescheduling energy, and transactions due to real-time market rescheduling energy. The comprehensive benefit distribution refers to profit distribution by combining economic marginal contribution of each resource and multi-index weighted comprehensive contribution. Economic marginal contribution refers to the increase in profit after participation of the source charge storage resources, indicating the contribution importance of the source charge storage resources. The multi-index weighted comprehensive contribution refers to dividing the contribution index of the source load storage resource into an energy transaction contribution, a standby service contribution, a power adjustment contribution, an economic marginal contribution and an energy storage service contribution, and weighting the contribution index to obtain the comprehensive contribution degree of the source load storage resource, so as to determine profit allocation of the source load storage resource.
