Reliability and risk assessment of post-contingency demand response in smart distribution networks

Abstract

This paper presents a comprehensive framework for the assessment of reliability and risk implications of post-fault Demand Response (DR) to provide capacity release in smart distribution networks. A direct load control (DLC) scheme is presented to efficiently disconnect DR customers with differentiated reliability levels. The cost of interrupted load is used as a proxy for the value of the differentiated reliability contracts for different customers to prioritize the disconnections. The framework tackles current distribution system operator (DSO)'s corrective actions such as network reconfiguration, emergency ratings and load shedding, also considering the physical payback effects from the D..
