Energy Storage System for Local Generation in a Grid-connected Microgrid : Sizing and analyzing an energy storage system for the Tezpur University campus
Reducing the emissions is an important step in orderto reduce the global warming. At Tezpur University in the Assamregion in Northeast India a project is being performed which willtry to reduce the use of diesel for back-up generation and partlyreplace this with other sources of energy. In 2018 a 1 MW PVplantwas installed as a part of this goal. However, since theconsumption and the PV-production are not synchronized someof the energy goes to waste.This thesis will consider how an energy storage system (ESS)can help to increase the usage of the power produced by thePV-plant. It will also assess the best type and size of the system.In addition to this, a simple economical analysis was performedto determine the profitability of the project.First, data regarding the system at Tezpur University wasgathered. The data of interest was the production of the PVpanels as well as the consumption. This data was then processedso that the consumption and production could be observedfor each hour a typical day. By comparing these two theoverproduction which goes to waste could be estimated. Byevaluating how much energy produced from diesel which couldbe replaced by the ESS an assessment of the savings per yearcould be made. From this the payback period was calculated forthe different size ESS.The results show that a battery energy storage system (BESS)using lithium-ion batteries is the preferred solution in this case.Assuming that 50 % of the life expectancy of a battery is areasonable payback period the maximum size of the battery is127 kWh. The optimal placement of the BESS is at substation 4as the overproduction is the greatest in this area and as there isalso a large load the stored energy would be used fully each day.A battery size of 90 kWh was suggested by the E4T MicroGridproject and considering the payback period this is a reasonablesize for the BESS. ; Att minska utsläppen är ett viktigt steg iatt minska den globala uppvärmningen. Vid Tezpur Universiteti Assam i nordöstra Indien genomförs nu ett projekt somskall ...
