Because of the high penetration renewable energies and installation new control devices, modern distribution networks are faced with voltage regulation challenges. Recently, rapid development artificial intelligence technology has introduced solutions for optimal problems dimensions dynamics. In this paper, a deep reinforcement learning method is proposed to solve two-timescale problem. All var...

Decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. Conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. In this paper, a new droop control s...

To deal with the DC-link overvoltage during high-voltage ride-through (HVRT) of wind turbine, a coordinated voltage control (CDVC) scheme is proposed for enhancing HVRT performance offshore doubly-fed induction generator (DFIG) turbines equipped supercapacitor energy storage system (SESS). This formulated as two-stage problem depending on depth grid swell, which can prevent damaging converter r...

Full power rating three-level neutral-point clamped (3L-NPC) back-to-back power converters seem promising for wind turbine systems with high power. Direct Model Predictive Control (DMPC) is an attractive technique, in particular, for multi-level converters. Voltage sensorless control makes the voltage measurements obsolete. This work proposes and verifies an Initial Bias Compensation based Virt...
