“…No matter the static economic dispatching or dynamic economic dispatching, there are many different limiting factors that need to be controlled reasonably in the generating process of the generator set, which is also a very complicated task. These factors include: the power demand changes of users, power loss of system transmission lines, valve point effect of generator set during operation, different power generation limits of each generator set, and power change limits of increasing or decreasing unit output in each period [12]. Improper consideration of these constraints will lead to potential increases in operating costs and pollution emissions during power distribution in microgrid systems, so it is critical that the power output of these generating sets is correctly allocated.…”

As fossil energy is increasingly depleted, promoting the integration of renewable energy into the grid and improving its utilization rate has become an irresistible development trend in China’s power industry. However, the volatility of wind power increases the difficulty of economic dispatch in power systems. With the rising participation of wind power in the system, the complexity of traditional microgrid dynamic scheduling problems has increased, transforming into a dynamic economic scheduling problem for wind power thermal power hybrid microgrids. Starting from the concept and research significance of economic dispatch, this article analyzes the current research status of microgrid economic dispatch as well as the impact and influencing factors of wind energy grid connection on it. It summarizes the research performed by scholars in two aspects: scheduling models and solving algorithms in static dispatch, as well as how to deal with wind power randomness in dynamic dispatch and how to balance environmental protection while ensuring economic maximization. Finally, the existing problems in current research were summarized and future development directions were prospected. This research has important application prospects in improving the economy of the system and protecting the ecological environment.

“…Therefore, a multiobjective approach has been used to deal with these two conflicting objectives in the combined CHP economic and emission dispatch (CHPEED) problem. The CHPEED multi-objective problem has been solved using numerical polynomial homotopy continuation (NPHC) [16], the normal boundary intersection method [17], time-varying acceleration PSO [18], GWO [19], and multiverse optimization [20].…”

In this paper, the economically self-sufficient microgrid is planned to provide electric power and heat demand. The combined heat and power-based microgrid needs strategic placement of distributed generators concerning optimal size, location, and type. As fossil fuel cost and emission depend mainly on the types of distributed generator units used in the microgrid, economic emission dispatch is performed for an hour with a static load demand and multiple load demands over 24 h of a day. The TOPSIS ranking approach is used as a tool to obtain the best compromise solution. Harris Hawks Optimization (HHO) is used to solve the problem. For validation, the obtained results in terms of cost, emission, and heat are compared with the reported results by DE and PSO, which shows the superiority of HHO over them. The impact of renewable integration in terms of cost and emission is also investigated. With renewable energy integration, fuel cost is reduced by 18% and emission is reduced by 3.4% for analysis under static load demand, whereas for the multiple load demands over 24 h, fuel cost is reduced by 14.95% and emission is reduced by 5.58%.
