Dynamic programming formulation of Micro-Grid operation with heat and electricity constraints

Abstract

This paper addresses unit commitment for Micro-Grid optimization including renewable sources, working under deregulated power market. As Micro-Grid supplies both of heat and electricity consumer, operational optimization must be done in coordination. So far in this paper, renewable energy sources are considered to be negative load, and batteries, as well, are used as the load flattened device to raise possibly operational function. In state of solution, Dynamic Programming Method has been developed that solve out the maximum profit Micro-Grid that owner might achieve from energy trading in a day, either in isolated or connected mode.
