Resilience-assured protective control of DC/AC inverters under unbalanced and fault scenarios
This paper presents a model predictive control (MPC)-based scheme in power distribution systems focused on protective control of distributed energy resources (DER) assuring performance resiliency under faults and unbalanced conditions. This scheme is applied to a three-phase four-leg voltage inverter which is able to effectively respond to unbalanced loads at the edge connection of the power electronics to the distribution grids. 3-D space vector modulation is utilized for synchronization and load control, enabled through a minimized weighted cost function. To achieve a smooth-enough recovery and resilient waveform response in the face of the grid prevailing conditions, a passive predictive sub-space modulation is enforced. In order to demonstrate the effectiveness of the proposed platform, a modified IEEE 13-bus feeder is utilized as a test case. Numerical investigations on different fault scenarios validate the effectiveness of the proposed protective control scheme helping secure the voltage source inverters against overloads.
