Optimal Operation Scheduling of a Microgrid in Presence of Energy Hubs Considering Energy System Security and Demand Response

Operation scheduling of electrical distribution systems will be more challenging in the future thanks to evolution of this system. Presence of energy hub, natural gas infrastructure and distributed energy resources in this system will be the main challenge of the system operators. In this paper operation scheduling of energy carriers and reserves considering security constraints of networks in presence of interconnected energy hubs is proposed. Both electrical and Natural gas networks’ constraints are considered in this study. The objective function of this model is operation costs for supplying electrical and thermal loads. The MGO (Micro grid operator) is in charge of optimal scheduling of supplying loads as well as maintaining technical constraints. The optimal scheduling of resources is obtained. Also, Results show reduction of costs due to commitment of responsive loads. Moreover, interdependence of electricity price and natural gas consumption shows the importance of integrated optimization of electricity and gas networks.
