Multi-Objective Stochastic Expansion Planning of Multi-Carrier Energy Distribution Networks Considering Customer-Owned DG Units

Abstract

In this paper, a multi-objective framework is proposed for expansion planning of energy hubs, natural gas and electricity distribution systems considering the uncertainties of renewable sources and demand. The aim is to reduce total investment and operation costs through coordination among different stakeholders. In this regard, planning problems from each stakeholder’s point of view are modeled as individual optimization problems. Subsequently, a multi-objective framework for optimization of conflicting interests of different stakeholders is extracted and solved using the multi-objective genetic algorithm. The proposed model is applied to a multi-carrier energy distribution system and the obtained results are thoroughly discussed.
