2021 OCT 11 (NewsRx) -- By a News Reporter-Staff News Editor at Economics Daily Report -- New study results on sustainability research have been published. According to news originating from Semnan, Iran, by NewsRx editors, the research stated, “With the growing demand for electricity, the inability of governments to provide the necessary resources to invest in the electricity industry and the rising price of fossil fuels, the tendency is to study and pay attention to economic issues in power systems studies.”

The news reporters obtained a quote from the research from Semnan University: “In this paper a new modified version of gray wolf optimization (MGWO) is proposed to solve the unit commitment (UC) problem in a power system in case of uncertainty. Market price variation is the main source of uncertainty in the UC program. Therefore, a model based on normal probability density function (PDF) is present for reducing the market price uncertainty effect in the model. Simulations are done for a standard 10 thermal units power system, and the results of the optimization by the proposed MGWO are compared with the previous version of the GWO algorithm and particle swarm optimization (PSO) algorithm results.”

According to the news editors, the research concluded: “The simulation results confirm the superiority of the proposed MGWO algorithm over the two algorithms PSO and GWO.”
