Abstract
In this paper, we design multi-energy management strategy for power-supply participants, heat-supply participants and consumers in a microgrid. The objectives of the management strategy are to maximize the social welfare and to balance the energy supply and demands. With the transmission loss, the proposed social welfare model, subject to practical operation constraints, is formulated as a nonconvex optimization problem. Based on a sufficient condition, a equivalent problem transformed from the primary optimization problem is presented as a convex problem. A neurodynamic algorithm based Karush–Kuhn–Tucker(KKT) conditions and projection with fewer neurons is developed to regulate the resource output of each participant. The convergence of the applied algorithm is proved by Lyapunov function. Finally, numerical simulations are used to prove the effectiveness of the designed management strategy.
