Security Restricted Dispatch Optimization Using Improved LDOA Technique: In an Islanded Microgrid System

ABSTRACT Microgrids are a single entity that manages several distributed generators and linked networks. This is the most recent study field in which traditional and renewable technologies may be combined to address the difficulties of transmission losses and CO2 emissions. Making microgrids smarter and more efficient requires cost-effective scheduling. As a result, a lot of new technologies are moving in the same direction. The study presented in this paper relates to the optimum scheduling of an islanded microgrid with three conventional DGs, one wind farm, and one solar power plant. A new improved method Levy Dingo Optimization algorithm (LDOA) of already existing technique named as Dingo Optimization algorithm (DOA) is designed and successfully tested on 23 bench-mark functions. Further, this hybrid technique is implemented on Economic load and Emission dispatch, Combined Eco-nomic Emission Dispatch (CEED) by considering various integration of distributed generators which is going to share the load for 24 h. The efficacy of the proposed technique is tested and compared with some current techniques like GWO, PSO, SOS, DE, and WOA as well as with newly developed approaches like DOA. In all four instances, i.e., without taking into account solar energy, without taking into account wind energy, without taking into account renewable energy sources and considering all five sources, the suggested solution outperforms the existing strategies, indicating that it has a lot of potential in this field.
