Techno-economic analysis-based optimal incorporation of distributed energy resources in distribution network under load uncertainty

摘要

This paper addresses optimal incorporation of various distributed energy resources (DERs), ie wind, solar and electric vehicles (EVs), in distribution system for the purpose of minimisation of total real power loss, total cost and emissions produced from grid simultaneously. To achieve these proposed objectives and benefits, a multi-objective function has been formulated. In this study, various mathematical models of DERs have been used for analysing the impact on distribution system under uncertain load demand for 24 h. In addition, the charging/discharging concept of EVs during off-peak/peak hours of the grid has also been taken into consideration. This non-linear and non-convex optimisation task has been solved through Gbest-guided Artificial Bee Colony optimisation technique because of its robustness. However, from the obtained numerical outcomes through the proposed technique, it is observed that the integration of DERs is capable of reducing total real power loss, total cost and emissions to a great extent.
