Abstract
In today's society, the importance of creating highly reliable distribution networks cannot be overstated. Utilities face challenges in planning and developing these systems effectively, aiming to decrease costs and meet consumer demands. This research proposes a coordinated architecture that focuses on the integration of a Demand Response Program (DRP) to improve the reliability of power distribution networks. Specifically, in this paper the reliability improvement is presented through finding optimal price, location, and amount of participated load in demand response program considering automatic switches and ESUs in service restoration process in electrical distribution systems. Also, uncertainty of repair time for faulted equipment is considered in this paper. suggested objective is to minimize the Total Cost of the system (TC) by optimizing the placement of the price, location, and amount of participation loads. The TC includes the cost of customer interruption, energy not supplied, ESU participation, and DRP. To illustrate the applicability and efficiency of the suggested approach, it is applied to three cases on a test case. Additionally, a sensitivity study is conducted. The results demonstrate that optimizing the incentive and penalty costs leads to significantly reduced SAIDI index and total costs. Moreover, the value of the incentive and penalty costs is lower than the fixed ones in this study, resulting in increased participation of sensitive load points in DRP.
