Voltage Control of Microgrid using co-simulation between Powerfactory and FMUs in Matlab

Accommodating renewable energy power with its intermittent nature into the grid and maintaining voltage stability has been a focus of electricity-related research for a decade. The paper presents a practical co-simulation platform that supports the voltage control of microgrids. Voltage is controlled by changing the reactive power of PV systems and BESS (represented by FMUs in Matlab). In this paper, we develop an interface built in Python that allows us to connect and synchronize the time step among different software, simulators, or real devices. We then test and validate the co-simulation method by linking two widely-used software, Matlab and PowerFactory, to control the voltage in a microgrid. The proposed solution shows that co-simulation is practical and efficient in the operation and management of the grid.
