1. Introduction

As the world transitions towards a greener future, solar energy has emerged as a reliable and sustainable power generation option. However, the intermittent nature of solar power can pose challenges in meeting continuous energy demands. To address this issue, integrating energy storage systems with solar PV installations has become crucial.

2. Understanding Solar PV Systems

Solar PV systems harness sunlight and convert it into electrical energy through the photovoltaic effect. These systems consist of solar panels, inverters, and various components to capture, convert, and distribute the generated electricity. While solar PV systems are an effective means of harnessing renewable energy, they are subject to variations in solar irradiance and weather conditions.

3. The Need for Energy Storage

Solar PV systems produce maximum power during daylight hours when the demand for electricity may be low. Excess energy generated during these periods often goes unused and is wasted. Energy storage systems help mitigate this issue by storing surplus energy for later use. This stored energy can be utilized during periods of low solar irradiance or high electricity demand, ensuring a reliable and consistent power supply.

4. Introducing Solar PV Battery Integrated UPQC

Solar PV Battery Integrated UPQC combines the functionalities of a Unified Power Quality Conditioner (UPQC) with energy storage capabilities. UPQC is a power conditioning device that aims to enhance power quality by compensating for voltage sags, swells, and harmonics in electrical grids. By integrating a battery system, Solar PV Battery Integrated UPQC provides additional benefits of energy storage, improving the overall efficiency of the solar PV system.

5. How Solar PV Battery Integrated UPQC Works

Solar PV Battery Integrated UPQC consists of three major components: the solar PV array, the battery system, and the UPQC controller. The solar PV array generates DC power from sunlight, which is converted into AC power through an inverter. This AC power is then supplied to the load and simultaneously connected to the UPQC controller.

The UPQC controller constantly monitors the power quality parameters, such as voltage and current, and compensates for any disturbances or fluctuations. It ensures a stable and reliable power supply to the load. Simultaneously, the excess solar energy is directed to the battery system for storage.

During periods of low solar irradiance or high electricity demand, the battery system discharges the stored energy to supplement the power supply. This seamless integration of solar PV and energy storage optimizes energy utilization and improves the overall system efficiency.

6. Advantages of Solar PV Battery Integrated UPQC
