Assess students' ability to design and optimize a sustainable microgrid for a small community by applying solar PV sizing, battery storage selection and state-of-charge management, load scheduling/demand response, and trade-offs between capital/operational costs and greenhouse gas emissions; tasks include time-step energy-balance calculations, selecting storage/inverter capacity to meet reliability targets, creating a load-shifting schedule to reduce peak and costs, and comparing cost–emission outcomes across scenarios with quantitative justification of choices.
