The traditional unidirectional, passive distribution power grids are rapidly developing into bidirectional, interactive, multi-coordinated smart grids that cover distributed power generation along with advanced information communications and electronic power technologies. To better integrate the use of renewable energy resources into the grid, to improve the voltage stability of distribution grids, to improve the grid protection and to reduce harmonics, one needs to select and control devices with adjustable reactive power (capacitor batteries, transformers, and reactors) and provide certain solutions so that the photovoltaic (PV) converters maintain due to voltage. Conventional compensation methods are no longer appropriate, thus developing measures are necessary that would ensure local reactive and harmonic compensation in case an energy quality problem happens in the low voltage distribution grid. Compared to the centralized methods, artificial intelligence (heuristic) methods are able to distribute computing and communication tasks among control devices.

“…It is also highly recommended for large-scale factories that need their own regulated source of reactive power. In practical application, MCR reduces grid losses, improves power quality, optimizes power transmission, control operations automatically, increases reliability and simplifies maintenance [1][2][3][4][5][6][7]. The research and application of MCRs have been greatly developed thereby, leading to many different types [8][9][10].…”

Magnetic-valve controllable reactor (MCR) has become many researcher’s topic of the day because of its versatile use in power systems. MCR utilizes the concept of magnetic saturation to control power flows in the power grid. It is as simple to operate and maintain, and reliable as an ordinary transformer. However, magnetic-valve controllable reactor works under a more variety of complex excitation condition because of the superposition action of AC and DC excitations. This paper carefully discusses the distribution of magnetic field of MCR core, provides an understanding of the range of inductance adjustments and further analyzes the working current waveform. Based on that, the finite element analysis software ANSYS Maxwell is used to design and examine a 3-D prototype model under different control voltage levels. The method of transient solution is applied for the reason being that it simultaneously has both AC and DC voltages. The AC voltage is kept constant while the DC voltage is varied from the minimum to the maximum rated value. The simulation results confirm that the magnetic-valve controllable reactor works in the saturation region of the magnetization curve under the combined excitation of AC and DC. The inductance adjustment range shows that the MCR inductance value can be smoothly and continuously varied. In addition, the working output current contains little odd-order harmonics that can be mitigated if filtering device is used or the magnetic valves are designed carefully. By observing the simulation results and analysis, one can gain a thorough understanding of MCR under actual working condition. It provides a reliable basis for the performance design of magnetic-valve controllable reactor.
