Improving Solar PV System Performance through FOPID Control and MPPT Optimization

Problem Definition

Maintaining voltage stability in power systems is essential for ensuring reliable operation, particularly as the penetration of solar power continues to increase. Reactive power compensation is crucial for managing electric and magnetic fields in transmission and distribution networks, with Static Synchronous Compensators (STATCOMs) being a popular solution. However, current control strategies based on Proportional-Integral (PI) controllers have been found to have limitations, including issues such as overshoot, oscillations, and poor transient response. These shortcomings highlight the need for a new, more effective control strategy that can address these issues while also enabling solar power systems to operate at their full potential within the grid. By developing a novel control strategy that can enhance reactive power compensation and overcome the drawbacks of existing approaches, we can further improve grid voltage stability and support the reliable operation of power systems.

Objective

The objective of this project is to develop a novel control strategy using Fractional Order Proportional Integral Derivative (FOPID) for Static Synchronous Compensators (STATCOMs) in order to improve reactive power compensation for solar power systems. By addressing the limitations of current Proportional-Integral (PI) controllers such as overshoot, oscillations, and poor transient response, the project aims to enhance control performance, robustness, stability, and flexibility. Additionally, integrating Maximum Power Point Tracking (MPPT) into the control strategy will optimize power extraction from solar PV panels, ensuring maximum power output under varying environmental conditions. The ultimate goal is to improve grid voltage stability, support the reliable operation of power systems, and enhance the efficiency of solar energy utilization by overcoming the drawbacks of existing control strategies.

Proposed Work

The existing PI-based control strategies have limitations such as overshoot, oscillations, and poor transient response. By utilizing FOPID control, the project aims to achieve improved control performance with better robustness, stability, and flexibility compared to traditional controllers. Additionally, the integration of Maximum Power Point Tracking (MPPT) into the control strategy will optimize power extraction from solar PV panels. The MPPT concept ensures that the solar system operates at its maximum power point regardless of environmental variations, thus enhancing the efficiency of solar energy utilization.

Furthermore, the project will develop an algorithm that synergistically combines FOPID control with the MPPT approach to ensure maximum power extraction from solar panels under varying environmental conditions.
