Microgrid solar resources: peak of 100 - 1500 kW (you to decide). Total daily solar energy input assumed to be rated power x 4 hours in middle of day (in the shoulder period); zero in peak and offpeak periods. Microgrid battery energy storage: 5000 - 7000 kWh (you to decide). 80% of the stored energy in the batteries can be extracted. You can see that it is an optimisation problem, with two variables to optimise - solar power rating and battery capacity. The problem lends itself to a tabular spreadsheet approach. Use any software package that you find the most convenient. Required Analysis: You are to do 4 case studies, Cases 0 to 3, as below: Case 0. Base case. Normal situation. Assume all solar resources are available and grid top-up is available all day. Assume that the batteries start the day (at midnight) 50% charged (from the previous 24 hours). By experimentation, determine the combination of battery storage capacity and solar power rating that will supply all loads in the Microgrid and finish the day with the batteries back to 50% storage, ready to commence the next day. Case 1. Link failure. Assume full load and solar output, but the link to the main grid fails and is unavailable during all the peak and shoulder period (i.e., islanding occurs). Determine any load shedding to be done. Case 2. Cloudy day situation. Assume that the total solar energy received all day is only 70% of the normal rating (Case 0) and that the corresponding load is 95% of normal loading and that the link to the main grid is again unavailable during all the peak and shoulder periods. Again, determine any load shedding to be done. Case 3. Grid emergency. Assume full load and solar output, but the main grid EMC requests an emergency injection of 100 kW from the Microgrid during all the peak and shoulder period. Again, determine any load shedding to be done.
