Abstract: Intermittency of wind and solar potential necessitate for development of new systems, bringing additional co3mplexity to power system operations and planning. This has led to a new framework for improving the performance of solar Grid Tied inverters installed on the Low Tension Grid of Kerala. The aim is to introduce a Battery Intervention Power Supply (BIPS) integrated with the solar inverter that helps in smoothening the energy output of the inverter and in reducing the sub-harmonic oscillations in the output current waveform. It also helps to improve the performance of the inverter during the low irradiance levels. The excess power is stored in the BIPS during Peak Source Accumulation, power disruptions and when outside the safe operating region of the inverter. This can also be utilized to meet local priority loads. The model of the battery used to study the performance is derived using non-linear regression analysis method of curve fitting. The paper introduces an improved solar plant that reduces the length of distribuion lines delivering good power quality and maintaining grid stability with reduced intermittency of power flow.
