    Grid Tie Solar System
    (Daffodil International University, 2020-10-10) Shakil Ahmed, Md.; Al-Amin, Md.
    Distribution level solar energy generation has gained importance and popularity, because it helps create a sustainable electricity system while reducing the harmful environmental impacts our current power systems have. The simple model has a photo-current source, a single diode junction and a series resistance, and includes temperature dependences. When settings are right, the grid- connected PV system supplies the additional power, moreover consumption by the connected load, to the utility grid. This study proposes an alternative energy source, a laboratory scale grid- connected photovoltaic system. The control of DC/DC converter is ensured by using perturb and observe method in order to make photovoltaic panels work at maximum power point (MPP) in all cases. A grid-tied solar power inverter does DC-to-AC conversion and minimizes energy transfer losses. The inverter also has an anti-islanding feature, which senses a power outage and prevents back-feeding through isolating the circuit. The circuit’s breakers isolate electrical components and protect the circuit.
