The quadrants of reactive power also provide important reference information for the operation and control of power systems, helping to optimize the efficiency and stability of power system operation.In power systems, reactive power and active ...
This includes the modelling of PV module and the power conditioning unit interfacing the PV to the utility grid with proper power flow control. The output of the PV panel is connected to the DC–side of the voltage source inverter for interfacing to the grid. The maximum power point tracking, grid synchronisation, ...
The voltage difference between two nodes is strongly affected by reactive power flow. In contrast to frequency control, node voltage control must be achieved locally. ...
This paper presents a voltage and frequency controller with neutral current compensation in a stand alone wind energy conversion system (WECS) employing an asynchronous generator. ...
Reactive Power Optimisation (RPO) is an important issue in deregulated electricity market. ...
The increasing energy demands, insufficient availability of power generation and increasing global environmental problems, need alternate/green power sources. Among the different green power technologies such as wind power, photovoltaic, gas turbine and fuel cell, the fuel cell-based distributed generation is considered as one of ...
To achieve these purposes, back-to-back pulse width modulation (PWM) voltage source converters (VSCs) are employed to excite the DFIG rotor. To control the power converters, two regulation loops, following the field oriented control (FOC) method, have been conceived. The first loop, dedicated to the rotor converter, enables a decoupled ...
This paper presents the impact of FACTS controllers on the long-term dynamic stability of power systems connected with wind farms based on doubly fed induction generator systems. The stability assessment is made first for a three-phase short circuit without the FACTS controllers in the power network and then with the FACTS ...
The FACTS devices like SVC's, STATCOM and custom power devices like DSTATCOM have been able to solve the voltage flicker problems by rapidly controlling the reactive power. But, control of active power along with reactive power control helps to ...
This article presents reactive power compensation of isolated wind-diesel hybrid power system for realistic load disturbance using Matlab/Simulink. The mathematical model of the system based on Matlab/Simulink is developed. Reactive power control performance is compared using three different ...
Wind power producers need to comply with the hosting utility grid interconnection standards, e.g., voltage and frequency, as well as to provide controllable active and reactive sources of power. ...
Voltage control and reactive power compensation in a distribution network with embedded Wind Energy Conversion System (WECS) represents the main concern of this paper. ...
This paper presents reactive power control of isolated wind-diesel-micro-hydro hybrid power system for realistic load disturbance using matlab/simulink. The mathematical model of the system based on matlab/simulink is developed. Reactive power control performance is compared ...
