This paper presents a simple and robust fuzzy logic with Adaptive linear Neuron (Adaline) controller. It is used for controlling the Direct driven Permanent Magnet Synchronous Generator (D-PMSG) based Wind Energy Conversion System(WECS) supplying three phase loads. In practice the loads are non-linear in nature and therefore harmonics are injected in to the generating system. By this PMSG is affected by these harmonics and leads to poor voltage regulation and requires adjustable reactive power source. The fuzzy logic is employed as control strategy for machine side converter to maintain the constant DC voltage supplying to GSC without any additional DC-DC converter. The Adaline Based Load Side Converter (LSC) is employed to mitigate the harmonics and delivering the reactive power co-ordinately to load. A dynamic model of PMSG feeding Linear / Non linear loads using synchronous reference frame method are developed for predicting the system behaviour under various loading conditions. The result shows that the wind turbine operates at variable speed with optimized performance and the power quality improvement can be achieved in terms of minimum total harmonic distortion (THD) according to the IEEE 519 standard. The Adaline controller is used for accurate estimation of phase and frequency at the point of common coupling (PCC). The feasibility of the proposed system model and integrated control strategy are verified using MATLAB/Simulink simulations.

Renewable energy sources, which are expected to be a promising alternative energy source, can bring new challenges when connected to the power grid. A large amount of wind turbines are connected to the electrical power system in order to mitigate the negative environmental consequence of conventional electricity generation. While connecting the wind turbine to grid it is important to understand the source of disturbance that affects the power quality. FACTS devices are found to be very effective for stability enhancement followed by a disturbance. Static Synchronous Compensator (STATCOM) which is a shunt device of FACTS family is efficient in regulating voltage either by absorbing or by generating reactive power. STATCOM can provide fast and efficient reactive power support to maintain power system voltage stability. This paper proposes a Hybrid control model for STATCOM that controls the voltage during a disturbance. The proposed controller is implemented to the STATCOM under MATLAB/SIMULINK environment. In the simulation test, the hybrid control shows consistent excellence under a severe disturbance like three phase fault. Keywords: STATCOM, power quality, FACTS, power grid, hybrid controller. I.INTRODUCTION Electric power system is a complex system in its structure and operation is facing many challenges day by day. The major problem in power system is its instability. Power system stability is the capability of the system to maintain an operating equilibrium point after being subjected to a disturbance for given initial operating conditions. Traditionally voltage regulation is performed by the excitation system and thereby help in controlling the system voltage. Suitable devices like Automatic Voltage Regulators (AVR) are used for the regulation of generated voltage. AVR's normally maintain the generator voltage magnitude at a specified level. AVR's are extensively used on the dynamic or steady state stability of the power system as low frequencies oscillations persist for a long period and may affect the capability of power transfer. Electrical power demand is rising at a very higher rate because of rapid industrial development. In order to satisfy the demand, power transmission has to be raised along with the existing facilities. Thus it is essential to concentrate on the power flow control. The power system should be flexible to adapt itself to any momentary changes in system conditions. In an AC power system, there must be a balance between the generated power and variations in load demand while keeping the system frequency and voltage levels as constant. If the generation is not sufficient, the voltage and frequency drop and the load decreases to balance the total generation minus losses in transmission. But there are only a few percent margins for such a self-regulation. Hence the system is collapsed. Generator excitation controller normally improves stability for smaller faults but not suitable for larger faults that occur near to generator terminals. Thus, traditional methods have to be rev...

Unlike the traditional method for power quality improvement and low-voltage ride through (LVRT) capability enhancement of wind farms, this paper proposes a new wind power integrated system by means of an inductive filtering method, especially if it contains a grid-connected transformer, a static synchronous compensator (STATCOM) and fully-tuned (FT) branches. First, the main circuit topology of the new wind power integrated system is presented. Then, the mathematical model is established to reveal the mechanism of harmonic suppression and the reactive compensation of the proposed wind power integrated system, and then the realization conditions of the inductive filtering method is obtained. Further, the control strategy of STATCOM is introduced. Based on the measured data for a real wind farm, the simulation studies are carried out to illustrate the performance of the proposed new wind power integrated system. The results indicate that the new system can not only enhance the LVRT capability of wind farms, but also prevent harmonic components flowing into the primary (grid) winding of the grid-connected transformer. Moreover, since the new method can compensate for reactive power in a wind farm, the power factor at the grid side can be improved effectively.
