Distributed Real-time Optimal Power Flow Strategy for DC Microgrid Under Stochastic Communication Networks

This paper addresses a distributed real-time optimal power flow (RTOPF) strategy for DC microgrids. In this paper, we focus on the scenarios where local information sharing is conducted in stochastic communication networks subject to random failures. Most existing (OPF) algorithms microgrid require all controllers work concert with fixed network topology maintain zero gap between estimated global constraint violations. Thus, high reliability of required ensure their convergence. To address issue, proposed RTOPF tolerates failures and can seek optimum constant step size considering operation limitations microgrid. These aspects make suitable optimization, particularly when not reliable. addition, does from non-dispatchable devices, thereby reducing number sensors system. The convergence equilibrium points are theoretically proven. Finally, simulations 30-bus performed validate effectiveness designs.
