1. Introduction
The increasing demand for clean and sustainable energy sources has led to the rapid development and implementation of renewable energy systems, such as PV and wind power systems. These systems offer several advantages, including a significant reduction in greenhouse gas emissions, low operating costs, and minimal environmental impact. However, the intermittent nature of these energy sources poses a significant challenge in their integration into the grid, as the power output varies with weather conditions and time of day. This variability can cause instability in the grid, leading to disruptions in power supply.
The integration of energy storage systems with PV and wind power systems offers a solution to this challenge, as it enables the storage of excess energy generated during periods of high energy output for use during periods of low energy output. One of the critical components in energy management and control in renewable energy systems is the maximum power point tracking (MPPT) algorithm, which ensures that the PV and wind systems operate at their maximum efficiency.
2. Fuzzy Maximum Power Point Tracking
Fuzzy logic is a control strategy that uses a set of rules and membership functions to convert input variables into output variables. Fuzzy MPPT is a control strategy that uses fuzzy logic to optimize the operation of the PV and wind systems, enabling them to operate at their maximum efficiency. Fuzzy MPPT algorithms can handle the non-linear and dynamic characteristics of renewable energy systems, making them an ideal control strategy for PV and wind power systems.
3. Grid-Connected PV System with Fuzzy MPPT
A grid-connected PV system consists of PV panels, an inverter, and a grid connection. The MPPT algorithm controls the power output of the PV panels, maximizing the power output by tracking the maximum power point (MPP) of the PV system. The fuzzy MPPT algorithm adjusts the duty cycle of the converter to maintain the MPP under varying weather conditions, such as changes in solar radiation intensity and temperature.
4. Grid-Connected Wind System with Fuzzy MPPT
A grid-connected wind system consists of a wind turbine, a generator, an inverter, and a grid connection. The MPPT algorithm controls the power output of the wind turbine, maximizing the power output by tracking the MPP of the wind system. The fuzzy MPPT algorithm adjusts the blade pitch angle of the turbine to maintain the MPP under varying wind speeds and turbulence.
