Optimized scheduling method for energy storage system participating in multiple application fields

Abstract

The invention relates to an optimal scheduling method for an energy storage system participating in multiple application fields, which comprises the following steps of: firstly, customizing economic and technical indexes to be considered and relative importance degrees among the indexes by a user, and establishing an AHP (Analytic Hierarchy Process) comprehensive evaluation index; establishing a day-ahead optimization model taking economic benefit optimization as a decision-making target and an intra-day optimization model taking wind power output error minimum decision-making as a target, and then establishing an upper-layer optimization model taking AHP comprehensive evaluation index optimization as a decision-making target; according to historical data simulation operation, output distribution of energy storage in different application fields is determined, the problem that the utilization rate of energy storage equipment is insufficient is avoided to the maximum extent, and the synergistic effect between applications is effectively utilized; the analytic hierarchy process is adopted for comprehensive benefit evaluation, indexes are selected according to the actual situation of the power grid and the subjective demand of a user, and the importance degree of the indexes is set, so that the method has wide applicability; the energy storage system optimization scheduling method has important reference value for formulating an energy storage system operation scheme, guaranteeing reasonable benefits of energy storage investment manufacturers, improving the absorption capacity of a power grid to new energy and improving safe and stable operation, and is a promising energy storage system optimization scheduling method.

Problems solved by technology

If too much capacity and wind power fluctuations are put into operation, the utilization rate of the energy storage system will be low, and it will be difficult to guarantee the benefits of energy storage investors, which is not conducive to the long-term development of the energy storage industry; however, if the energy storage unit participates in frequency regulation and The energy market is dominant and the capacity invested in the field of wind power suppression is too small, the new energy acceptance capacity of the grid will be affected, resulting in frequent wind curtailment
