Multi-Objective Jaya Algorithm for Optimal Scheduling of DGs in Distribution System Sectionalized into Multi-Microgrids

In this paper, the power dispatch problem of distributed generators (DGs) for optimal operation of the islanded distribution system has been addressed. In order to mitigate the number of customers being affected by a fault at any remote location of the system, the islanded distribution system is sectionalized into several self-supplied microgrids such that reliable power can be supplied to maximum loads. These microgrids can be operated individually or joining with other microgrids such that rescheduling of DGs can be performed for attaining desired objective. The objectives considered in this paper are minimization of operating cost of DGs, system losses, voltage deviation individually. Furthermore, a multi-objective problem is formulated considering minimization of operating cost & losses, operating cost & voltage deviation and losses & voltage deviation simultaneously. While scheduling the distribution system, dispatchable DGs are used. A novel, algorithm-specific parameter-free meta-heuristic ...
