<span lang="EN-US">Model predictive control (MPC) has recently been ranked as one of the best modern technics for high voltage direct current (HVDC) based on source converter (VSC) transmission systems, since it is a simple controller, understandable and can be implemented easily, also dynamic fast response. The classic double closed loop PI controller many disadvantages such difficulty i...

In a conventional AC distribution system, the conservation voltage reduction (CVR) strategy is widely employed to lower down of specific load power consumption. The wide applicability demand side management (DSM) using CVR in stand-alone microgrid through VSI-based energy sources thrust area, that is, not examined yet and needs be explored. fast dynamics flexible control are characteristics vol...

Abstract UPS can provide stable electrical energy for sensitive loads when severe grid disturbance happens. A neutral point clamped (NPC) three-level voltage source converter is used as the circuit topology UPS. In this study, discrete mathematical model of derived and a single loop control strategy based on predictive presented. The proposed method has simple structure fast response speed omit...

In this paper, a new K-means clustering based approach for identification of voltage control areas is developed. Voltage control areas are important for efficient reactive power management in power systems operating under deregulated environment. Although, voltage control areas are formed using conventional hierarchical clustering based method, but the present paper investigate the capability o...

In view of the fact that current wind farms are mostly multi-wind turbines and it is difficult to accurately control a single turbine because its high dimension in optimization solution process, article proposes reactive power voltage coordinated strategy suitable for doubly-fed farms. The mainly divided into three layers. first group layer, which can obtain compensation task entire according i...

This paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. The hybrid DC power sources are connected to grid using power electronic converters include DC-DC converter and grid connected voltage source inverter. The power from hybrid power sources is controlled during voltage sag by designing of control strategy for DC-DC converter....
