Linear power flow characterization of DC power distribution systems for MEA optimization

Abstract:

The increased utilization of electrical energy in future aviation requires an efficient method to perform load flow for optimizing on-board operating conditions. Load flow are integral part in such assessments. Load flow of electrical networks are complex to solve and requires iterative methods to obtain a solution due to the non-linear relationship between voltages and currents. This paper addresses the complexity of load flow for DC systems and presents a linear model that does not require to be solved iteratively and can be included in Mixed Integer Linear Programming (MILP) formulations to allow operational metrics optimization such as loss minimization while ensuring convergence to global optimum. Load flow results have shown that the deviation margin is considerably small compared to traditional load flow methods.
