Allocation of Distributed Energy Resources for Microgrid Optimal Scheduling Considering Uncertainty

In this paper, a microgrid including a solar panel, a battery energy storage system and a diesel generator as the backup source are optimally is designed. The microgrid is considered as a part of a distribution network, that could be considered as local area. As microgrids can operate in grid-connected mode, the proposed algorithm investigates the minimization of the distribution network power loss, the amount of imported power from the utility and the curtailed load in case of emergency. The main purpose of the proposed algorithm is to minimize the overall investment, replacement and operation and maintenance costs for a microgrid. This article suggests a Lightning Attachment Procedure Optimization Algorithm to optimally design the problem of sitting and scheduling of microgrids in distribution systems. Both problems are solved simultaneously. The proposed approach is applied on 33-bus test system, and the results are discussed. Fast convergence, best global answer finding, and robustness are the characteristics of the proposed method, which are concluded from the results and discussion.
