Abstract:Energy storage technology is an effective means of solving the problem of having a high proportion of wind power consumption and improving system reliability. However, the different function orientation of energy storage, and the selection of typical load and wind power output curves will affect the configuration result of energy storage. In order to study the rules of energy storage allocation, multi parameter energy storage allocation models considering the uncertainty of wind power, wind power climbing and wind power consumption respectively are established. The configuration of different functions of energy storage is studied. Then, based on the principle of single variable and correlation analysis, the influence of various parameters in the system on energy storage allocation is quantitatively studied. The results show that reasonable access of wind power can reduce the required energy storage capacity, and the reasonable access node can effectively reduce the network loss; the maximum energy storage capacity needs to be configured when only relying on energy storage to solve the problem of wind power consumption. The time of use price is the main price determining the allocation of energy storage capacity. Among the system parameters, the wind power installed capacity has the greatest impact on the energy storage capacity and peak valley difference.
