SMES installation study on wind turbine based on ant colony optimization under load shedding condition

Energy needs are currently still dominated by fossil fuels, so efforts are needed to increase the use of new and renewable energy. Coal fired power plants (CFPP) are one of the industries that use it, where the main fuel of the plant is coal and mixed fuel with biomass as co-firing. Empty oil palm fruit bunches (EOPFBs) are biomass that has geat potential to be used as a mixed fuel because of its very abundant availability, especially in Riau Province. However, empty oil palm fruit bunches (EOPFBs) has high content of potassium and chlorine, and a low combustion calorific value. It is necessary to treat the EOPFBs to have a good quality. This research aims to produce biocoal from biomass by reducing potassium and chlorine content by using peat water, as well as increasing the calorific value of oil palm empty fruit bunches by the torrefaction process. The washing process is carried out with variations in time and flow discharge, namely 5-60 minutes and 2-5 LPM. While the torrefaction process is carried out with variations in the time and temperature of torrefaction, namely 30-60 minutes and 200°C-300°C. The result of this research conducted produced potassium and chlorine levels of 3.7% and 1.53%. While the largest calorific value is 7470.59 kcal/kg at a processing time of 60 minutes and a torrefaction temperature of 300°C and an energy yield of 78% at a time and temperature of 30 minutes and 200°C.
