Inverter design at photovoltaic for distributed generation networks

Abstract

The photovoltaic generator is a renewable energy generator and this generator can be used as a DG because it is an environmentally friendly generator and can be stored close to the load because it does not cause pollution to consumers who are near the plant. Photovoltaic generator requires an inverter to convert the voltage generated by PV (DC voltage) to the voltage needed by the grid (AC voltage). In this study, the data obtained is the planning of DG installation in Karimunjawa. However, there is no harmonics calculation in the network. So that requires the design of an inverter in order to analyses the harmonic generated and the effect of harmonics on the grid. Not only inverters, this generator also needs a boost converter because the voltage generated by PV is insufficient to convert into a 400 Volt AC voltage. The inverter will use the PWM technique which will convert the DC voltage to AC and use an LC filter to refine and reduce the harmonic generated by the inverter. Simulation in this research is to found value of the component in LC filter and Boost Converter. After that the circuit will connect to the grid for analysis harmonic on the load.
