VOLTAGE REGULATION IN NETWORKED ELECTRICAL POWER SYSTEMS FOR DISTRIBUTED GENERATION: A CONSTRAINED SUPERVISORY APPROACH

摘要

In this paper a constrained control strategy based on predictive control ideas is used to regulate the voltage in electrical Medium Voltage (MV) power networks. The aim is to regulate the voltage at certain nodes of the network in the presence of Distributed Generation (DG) units and despite of various changing loads acting as exogenous disturbances. The voltage regulation problem is rephrased as a constrained tracking control problem by imposing that the voltages at certain loads have minimum deviation from their nominal values. Simulations studies show the effectiveness of the proposed approach.
