Fault restoration strategy for active distribution network considering multiple operating states of thermostatically controlled loads
In recent years,the proportion of thermostatically controlled loads(TCLs) in power distribution network has surged,and its power fluctuation and backflow characteristics seriously affect the implementation of fault restoration strategy of distribution network. Therefore,based on the traditional restoration strategy,considering the multiple operating states and adjustable ability of TCLs,a fault restoration strategy of urban distribution network based on dynamic load weight is proposed. The TCL aggregation-power models under multiple operating states are established. According to the change characteristics of TCL power and indoor temperature before and after the fault,the dynamic load restoration weight coefficients of different nodes are calculated. The proposed fault restoration strategy based on dynamic load weight is analyzed and verified through a urban distribution system. The results show that,compared with traditional methods,the proposed service restoration strategy for active distribution network based on dynamic load weight can effectively improve the recovery electricity quantity of load,and provides an effective solution for the fault recovery strategy of urban distribution network with high-TCL penetration.
