Abstract:

It is the aim of Cranfield University to improve the self sufficiency of the campus energy supply. One of the ways to do so is to introduce renewable energy. These are, however, affected by intermittency in energy supplies and thus pose challenges to the grid stability. Energy storage systems are widely recognised as one of the main ways to make renewables more reliable and also allow for peak shaving. Moreover, decreasing costs of such systems make it more attractive for those other than grid operators, such as Cranfield University. The aim of this thesis is to estimate the optimal parameters of such a solution (power and capacity), through an analysis of campus electricity consumption and afterwards to evaluate the financial feasibility for each system via net present value evaluation techniques and sensitivity analysis with different variables to determine under which conditions they are feasible. Capacity was calculated to 5 412.85kWh and power to 902.12kW. The approach showed that none of the five selected technologies were not economically feasible at given set of conditions. Conducted sensitivity analysis suggests that significant decrease of initial investment, longer payback period or increase in price of electricity make chosen technologies viable. The paper concluded that capacity and power parameters might be further used by the Facility office of Cranfield university on the field of electricity self sufficiency. It also concluded that the facility office might use its own confidential data to reach more accurate outcome.
