CONTROL DEVICE FOR OPTIMIZING LOCAL ENERGY NETWORK

Disclosed is a control device capable of reducing COemission and primary energy consumption, as well as energy supply cost, to lowest possible levels in optimal energy management. In repeatedly generating two or more energy balance candidates for each unit time for the outputs of the electric power grid and thermal accumulation unit based on combinations of varied values of the output ratios of a CHP, an RES, a thermal energy supply system, and an electrical storage unit and the consumption ratios of electric and thermal loads until the convergence of the evaluation values of the two or more candidates reaches a convergence criterion.
