Research on the Optimal Configuration of Energy Storage in Distribution Networks Considering the Improvement of Frequency-Voltage Stability
摘要
Abstract
With the large-scale access of a high proportion of new energy,the frequency and voltage stability of the distribution network has significantly decreased.Therefore,an optimal configuration method for energy storage in the distribution network considering the improvement of frequency-voltage stability was proposed.Firstly,based on the inertia theory and the rotor motion equation,the relationship between the disturbance of new energy and the frequency change was derived,and a calculation method for the total installed capacity of the energy storage system considering the frequency safety constraint was proposed;secondly,based on the power flow calculation equation,the evaluation index of voltage stability of the distribution network was derived;then,comprehensively considering the voltage stability index and the installation cost of energy storage,the power flow balance of the distribution network,the node voltage,the construction of energy storage considering frequency safety,and the power constraint conditions of energy storage were constructed,and the energy storage optimization configuration model for improving the frequency-voltage stability was established;finally,the effectiveness of the proposed configuration method was verified through the simulation of the improved IEEE 33-node system example.The results show that configuring energy storage by the proposed method can control the frequency deviation value and the voltage stability of each line within a safe range under power disturbance.At the same time,it effectively reduces the economic cost of energy storage installation and helps to improve the frequency-voltage stability of the distribution network.关键词
