Abstract:
This paper considers the development of control algorithms for a simulation model of a fast automatic transfer switch incorporating an electrical energy storage device. The simulation model is developed in the MATLAB® software environment. The authors provide the formation block diagrams of the amplitude, frequency and inverter voltage phase when transferring the load from the emergency power grid to the storage device and the block diagram of the inverter voltage phase difference controller and the backup supply power grid. These structures implement the function of soft load switching from the main power grid to the energy storage device, followed by connection to the backup power grid. The resulting fast automatic back-up input device model, with an energy storage device, is operational. This is proved by the transients shown in the work.
Automatic load transfer is frequently used to solve problems related to the power outages occurrence in power supply systems. Many researchers have extensively examined the simulation modeling of these systems [1]–[3].
