Abstract
Self-healing is a capability of smart electricity distribution networks that enables the automatic restoration of the network in the event of a persistent fault. To restore the power supply to loads downstream of the fault location, adjacent feeders can be utilized. However, the use of backup feeders is subject to network technical constraints such as bus voltage levels and permissible line currents. One method to prevent the violation of network constraints during load restoration via backup feeders is the implementation of demand response programs. This paper examines the impact of Critical Peak Pricing (CPP), a price-based program, on the self-healing of smart distribution networks. Two models, exponential and linear, have been considered for modeling the CPP program. Additionally, the impact of different price surges on self-healing improvement has been analyzed. To make the results more realistic, various consumer participation rates in demand response programs have been taken into account. The proposed model has been evaluated using bus number 4 of the Roy-Billinton test system.
