Abstract:
‘Solar energy is clean and abundant but it’s also unpredictable. Output shifts with the weather, the angle of the sun, and the time of day, which makes relying on solar panels alone a challenge. This seminar explores how pairing solar photovoltaic (PV) systems with battery energy storage can solve that problem, and how smart control strategies keep the whole system running smoothly when connected to the grid. The study reviews existing research and builds a simulation model of a complete system: a PV array, a boost converter, a battery with a bidirectional DC-DC converter, a DC bus and load, a single- phase inverter, and a grid connection. To squeeze every watt out of the solar panels, an Incremental Conductance Maximum Power Point Tracking (MPPT) algorithm is used. PI controllers, inverter current control, and a Phase-Locked Loop (PLL) handle the rest keeping voltage and frequency stable and managing how power is exchanged with the grid. The seminar walks through how power is coordinated across the four key players the PV array, battery, load, and grid as conditions change throughout the day. When the sun is strong and demand is low, excess energy goes into the battery. When clouds roll in or demand spikes, the battery picks up the slack. The results show that combining battery storage with well-designed control logic leads to a more stable DC bus, better power balance, and a more reliable grid connected solar system overall.’
