Enhancing Power Quality of Grid-connected Wind Turbines through STATCOM-based Reactive Power Support

A. Praveena — 2025-10-10

Recently, voltage-source or current-source inverter-based various FACTS devices have been used for flexible power flow control, secure loading, and damping of power system oscillations. Due to the increasing penetration of Renewable Energy Sources (RESs) such as wind power, maintaining the stability and reliability of the power grid has become a significant challenge. The integration of induction generator-based wind turbines affects grid stability due to their inherent reactive power demand. A static synchronous compensator (STATCOM) is widely recognized as an effective solution for reactive power compensation. This study presents a comparative analysis of grid stability before and after the connection of STATCOM in a grid-connected wind energy system. The study focuses on evaluating key stability aspects such as reactive power support without implementing any control strategies for STATCOM operation. These findings highlight the potential of STATCOM as a robust solution for stabilizing wind power generation in grid-connected applications. The proposed scheme for the grid connected wind energy conversion system is simulated using MATLAB/SIMULINK.

The rising demand for sustainable transportation solutions has led to increased focus on Electric Vehicles (EVs) and associated energy-efficient technologies. This study presents the design, integration, and experimental validation of a regenerative braking-based self-charging mechanism for EVs. The proposed system captures kinetic energy typically dissipated during braking and converts it into storable electrical energy through a hybrid mechanical-electrical framework. Key components include a geared DC motor operating in generator mode, a flywheel for transient energy retention, and a power management circuit interfaced with a rechargeable battery. The prototype was evaluated under varying rotational speeds, and the corresponding voltage output was recorded. Experimental findings confirm the system’s capability to efficiently recover energy, thereby demonstrating its potential to enhance the energy autonomy and sustainability of urban electric vehicle platforms.

Power Generation Using Speed Breaker

Chavan Madhusudan — 2025-10-03

In the modern world, power has become indispensable to human existence. Energy is responsible for significant shifts in the financial status of every nation. Conventional forms of energy supply the majority of the energy generated in the modern world. However, the human population is growing rapidly, and the sources of regular electricity are running out. Additionally, these traditional energy sources promote contamination and a warming planet. Consequently, the development of sustainable, eco-friendly, and clean nonconventional sources for power generation is required. Here, we suggest a sustainable, unconventional power supply that is dependent on pioneers. Through the use of the jerking pressure that is wasted when a car passes a speed limit on the side of the road, we hope to brighten the streets. Utilizing the velocity limiter as a power source generating unit, we may harness the energy produced by moving cars and generate electricity. By means of an axle and sprocket system, the momentum of driving automobiles may be transformed into mechanical energy. The street lights will be powered by means of a generator, which can convert mechanical electricity into electrical electricity. Therefore, by using this method, we can conserve a lot of energy and satisfy our future demands.
