Evaluation Ratio of Renewable Hybrid Generation and Power Grid for Agriculture Electrical Load in Ratchaburi

Abstract

This research were proposed to consider ratio of renewable hybrid generation and power grid from transmission line network for agriculture electrical load in Rachaburi province. The economic parameters were to evaluate from through period 25 year, at interest rate 12%, and inflation rate 8.70% per year. So this research procedure start up the investigation of quantity electrical energy consumption each district. Meanwhile, the wind speed data was measured by Devis Vatage VUE Weather Station 6250 series tool. For the solar data was obtained from the ministry of energy at Kanjanaburi station in Thai Meteorological Department. From these all data, was evaluated elaborately by economic method of a1110 district found that the Saun-Phung was case study due to optimal area and electrical generating performance. The result of Suan-Phung was the break-even point at 2-14 year, based on the ratio of investment from two electrical source it mean that payback period and the capacity factor 0.25, interest return rate (IRR) 32%. So the result of net present value was the positive sign that mean there was the profit from investment of this project. The cost of energy was 60.59 baht per unit. As the results, the ratio of renewable hybrid generation and grid system were analyzed by sharing energy from 100% until 50% of agriculture electrical load in Suan-Phung that mean the power grid system start at 0% until 50% of agriculture electrical load in Suan-Phung for consider cost install and all economic indices. Found that, the Suan-Phung was area performance to invest renewable hybrid generation and grid system coordination.
