An efficient bi-objective approach for dynamic economic emission dispatch of renewable-integrated microgrids

“…As a rule, utilities should decrease the generation cost and the emission value as much as possible (Ghaedi et al 2020;Abbasi et al 2021). In contrast to the past decades when cost minimization was the only and most important objective for generating electric power, due to global concerns, such as environmental and human health concerns, caused by pollution of power generation, numerous regulations and solutions have recently been introduced to make the utilities able to decrease their harmful emissions, such as toxic gases exhalation, with possible least fuel cost (Krishnamurthy and Tzoneva 2012a). As mentioned above, a microgrid is developed as a small-scale power plant close to communities.…”

Economic Emission Dispatch Problem Solution Using Ant Colony Optimization of Micro-Grid in Island Mode

“…Therefore, the combined economic emission dispatch problem is formulated as a single optimization problem as follows: (6) Where; hi is the price penalty factor which is the ratio between the maximum fuel cost and maximum emission for each generator given by [11], [12].…”

“…In [11], [12]. The combined economic emission dispatch problem was evaluated for a mix of conventional and RES using Gradient method.…”
