Abstract

The lighting system consisting of LED street light system, power grid, photovoltaic (PV) arrays and inverting control system of grid-connected PV was investigated. The excess power generated from PV can be transported into power grid through an inverter which changes direct current (DC) into alternating current (AC) using current hysteresis control. PLC controls when to light LED and whether the battery or power grid gives power to LED according to a preset program. The simulation results show that PLC and the inverter control is an effective and simple method to realize these functions.
