Micro-Grid Economic Operation Contains Electric Boiler

Abstract:

When Micro-grid (MG) is accessed into large scale of wind turbines, whose anti-peak-adjusting characteristic will increases difficulty of economic and safe operation about MG. The ability to participate in the system peak-adjustment of micro-turbine will be greatly limited, as the CHP run as “heat-load-based” mode and the electric power outputting depends on heat load demand. So that, installing heat boiler to absorb surplus wind power in the anti-peak-adjusting periods, and to combine with CHP supplying heat energy will decoupling “heat-load-based” constraint, and then the flexible schedulability of MG will be improved. The minimum operating cost of MG is regarded as optimizing object, Genetic Algorithm is used to optimize operational status of each unit in MG, then the heat and electricity comprehensive optimization is realized.
