In today's rapidly evolving technological landscape, renewable energy systems have gned prominence as sustnable alternatives to traditional power sources. Among these, solar photovoltc PV systems stand out for their potential in generating clean electricity with minimal environmental impact. However, these systems face challenges such as variable output due to fluctuations in sunlight intensity and unpredictable weather conditions. This paper focuses on the utilization of an optimal control strategy to enhance the performance of a renewable energy system, specifically targeting solar PV systems.

The primary objective is to optimize power generation while ensuring stability and reliability, even under varying environmental conditions. The proposed approach employs advanced control algorithms that dynamically adjust key operational parameters based on real-time data from sensors monitoring sunlight intensity and battery state-of-charge SoC.

System Overview:

A renewable energy system typically consists of solar PV panels, a battery storage unit, an inverter, and chargingdischarging control mechanisms. The optimal control strategy involves modeling the system's dynamics to predict power generation under different conditions and coordinating these processes efficiently.

Optimal Control :

1. Predictive Modeling: This step uses historical data, real-time sensor inputs, and meteorological forecasts to estimate future sunlight intensity trs.such as the Gaussian process regression or artificial neural networks can be applied to predict these conditions accurately.

2. Adaptive Control Algorithms: Based on the predictive, control algorithms adjust parameters like charging rates for batteries, power output from solar panels, and operational modes of inverters in real-time to maximize efficiency and performance. These algorithms continuously learn from system performance data to improve predictions and adjustments over time.

Implementation:

To implement this strategy effectively:

• Data Collection: Accurate sensors are deployed to monitor environmental conditions and system status.

• Modeling: A comprehensive mathematical model is developed using the collected data for simulation purposes.

• Optimization Algorithms: Advanced optimization techniques, such as genetic algorithms or dynamic programming, are applied to determine optimal control strategies.

Case Study:

A hypothetical case study demonstrates the application of this method in a 10kW solar PV system with integrated battery storage. By integrating an optimal control strategy, peak efficiency was achieved at 95, compared to 85 without such intervention. This improvement resulted in higher energy output and reduced depency on grid power.
