Load-flow model of a multi-energy system

... energy development includes the creation of multi-energy systems (MES) with several energy carriers that are planned, designed and operated with essential coordination of their subsystems. When managing the development and functioning of such systems, optimization problems should be solved to minimize the cost of production, transmission and distribution of energy resources. Traditionally, the means of such minimization are the redistribution of the loads of generation sources, consumers and energy ...
