PROJECT TITLE :

Multistage Long-Term Expansion Planning of Electrical Distribution Systems Considering Multiple Alternatives

ABSTRACT:

This paper presents a replacement mixed-integer linear programming (MILP) model to unravel the multistage long-term expansion planning drawback of electrical distribution systems (EDSs) considering the subsequent alternatives: increasing the capability of existing substations, constructing new substations, allocating capacitor banks and/or voltage regulators, constructing and/or reinforcing circuits, and modifying, if necessary, the system's topology. The aim is to minimize the investment and operation costs of the EDS over a longtime planning horizon. The proposed model uses a linearization technique and an approximation for transforming the original downside into an MILP model. The MILP model guarantees convergence to optimality by using existing classical optimization tools. In order to verify the efficiency of the proposed methodology, a twenty four-node test system was employed.
