Research on the energy storage configuration strategy of new energy units
Abstract
In view of the increasing trend of the proportion of new energy power generation, combined with the basic matching of the total potential supply and demand in the power market, this paper puts forward the bidding mode and the corresponding fluctuation suppression mechanism, and analyzes the feasibility of reducing the output fluctuation and improving the stability level of the system by installing energy storage systems. At the same time, through qualitative social utility analysis and quantitative energy storage capacity demand measurement, this strategy fully takes into consideration multiple key factors affecting the amount of energy storage configuration and gives a quantitative calculation formula, which provides new energy suppliers with an optimal cost-effective algorithm to calculate the best economical energy storage configuration quantity. At the meantime, the supporting use of the fluctuation suppression mechanism and the configuration strategy realizes the goal of improving the operation stability of the power system through market-based means. Mathematical proof and the result of numerical example simulation show that the energy storage configuration strategy proposed in this paper is effective, also the bidding mode and fluctuation suppression mechanism are feasible.
