Abstract
A system and method perform electricity and heat load balancing within a community of energy nodes. The system includes a central control device to solve an optimization problem over a planning horizon and to run an allocation algorithm. Local agent devices communicate with the central control device. Each local agent device receives input parameters from an energy node. Each energy node includes electricity generation equipment, electrical heat-generating equipment, and power transmission equipment, electricity storage equipment and thermal storage equipment. The local agent devices operate the electrical heat-generating equipment based on an allocation instruction received from the central control device. The central control device receives status information from the local agent devices to determine an amount of energy to be converted from electricity to heat by the electrical heat-generating equipment of the energy nodes, to provide the allocation instruction to the energy nodes.
