A Reliability-based Strategy for Active Distribution Network Expansion Planning

The increase in the demand of the electrical loads is bringing challenges to power system reliability issues. Dealing with this, Distribution Network Expansion Planning (DNEP) is an approach used in Distribution Network (DN) to guarantee its reliability-related features. Another key solution for electricity provision is that the conventional distribution networks should be replaced by Active Distribution Networks (ADN) with Distributed Generations (DGs). The presence of these generation systems besides the DN, can change the rules of calculation of the reliability. This paper presents a DNEP-based framework while proposing a novel approach to identify the Expected Energy Not Supplied (EENS) in the ADN. A Mixed Integer Linear Programming (MILP) Framework is used to capture the optimal solution as a convex method. To guarantee the effectiveness of the presented approach, the IEEE 18 buses test case is used. The results verify that this model is cost-effective and can decrease the complexity of the calculation.
