Performance Analysis of Hybrid PV/Diesel Power Generation System with Battery Storage

The need for renewable energy sources is on the rise because of the acute energy crisis in the world today. India plans to produce 100 Gigawatts Solar power by the year 2020 under JNNSM. Solar energy is a vital untapped resource. The main hindrance for the penetration and reach of solar PV systems is their low efficiency and high capital cost. In this, we examine a schematic to extract maximum obtainable solar power from a PV module and use the energy for a DC and AC application. Integration of photovoltaic system with the diesel generator as a backup system is being escalated worldwide to minimize the consumption of fossil fuel resources. The hybrid power generation bring into productive action only by employing a suitable strategic control in operation of connected system. In this dissertation, the main objective is to deal with a control strategy that was developed to control the operation of diesel generator and charging/discharging of the battery storage system. The controlling action was detailed in such a way that it coordinates when the power is generated by the solar panel and when to operate the diesel generator and the battery so that the demands of the local utilities in the remote areas should be met with the installed generating system. The main focus in the management strategy of PV/diesel-battery hybrid system is to make the maximum usage of the renewable resource with battery storage system while making the operation of diesel generator in adverse conditions. The management strategy is described in detail through the data flow chart that narrates the different modes of operation considering the variant solar radiations.
