Method
The project method is shown in the flow chart below. It is important to note that the process we have developed in sizing, matching and selecting hybrid renewable systems could be applicable to many scenarios, and is completely transferrable.
STEP 1: Demand profiling
-Involved obtaining or creating demand profiles for each of our scenarios; for our community in the Present, 2020 and 2050.
-Required assumptions of future trends in energy efficiency, electrical appliance efficiency and behavioural changes.
STEP 2: Design of a community renewable scheme
-Involved creating a sizing procedure for hybrid small scale renewables: a key deliverable of the project.
-Involved a sensitivity analysis to verify such a sizing procedure.
STEP 3: Quantification of loss of match due to energy efficiency
-Involved matching sized supply with demand profiles in a demand-supply matching procedure.
-Involved using criteria such as match rate, grid interaction and economic savings to quantify each demand-supply match.
STEP 4: Selection Process
-Involved assumptions of economic and environmental considerations that a community must account for before deciding on such a scheme.
-Involved graphing various demand-supply matches options with respect to their assumed capital cost, analysing payback periods and constructing an environmental matrix.
