Sustainable energy-based generation systems, such as photovoltaic and wind turbine generation systems, normally adopt inverters to connect to the grid. These power electronic interfaces possess the characteristics of small inertia and small output impedance, which create difficulties to stabilize the voltage and frequency of a distributed power source. To deal with this problem, a Virtual Synch...

The power system is generally characterized by its size, complexity and time varying, beforehand unknown electrical load. Even slight changes in the settings can produce significant economic savings, because large electric power is transferred. Based on the characteristics of the power system and the nature of the secondary voltage control, it is clear that the optimal pilot bus selection plays...

The control used for the tapchanger of an LTC transformer or step-voltage regulator is a prime illustration of electronic technology advances applied to the power industry. Electro-mechanical (balance-beam and induction disc), discrete static, integrated circuit static and now digital designs have evolved over the past forty years. This increased product sophistication has made possible many fe...

in this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. in addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. in the proposed control metho...

Aiming at the bus voltage fluctuation caused by nonlinearity, limited change and uncertain factors such as deviation, load system parameter traditional droop control in DC microgrid, a precise scheme considering constraints is proposed. Firstly, parabolic used to replace linear improve accuracy of power distribution. On this basis, controller based on barrier Lyapunov function designed precisel...
