Description of COMPOSE (Compare Options for Sustainable Energy)

COMPOSE evaluates the feasibility of a user-defined energy option in a user-defined energy-economic system-wide perspective using user-selected methodology options.

Results include operational dispatch, economic costs, financial costs, fiscal costs, system-wide fuel consumption and CO2 emissions/cost-effectiveness, and metrics intermittency-friendliness and intermittency-volume as measures of smart performance.

In terms of CO2 emissions, COMPOSE offers the posibility of an assessment of an energy option's technical CO2 emissions taking into account the marginal producers of electricity and fuel in the respective markets. Any number of marginal producers of electricity and fuel can be selected for which the corresponding marginal production costs (calculated just as any other energy option) and the energy-economy system's spot market prices decides marginal CO2 impacts.

In terms of intermittency-friendliness and intermittency-volume, COMPOSE offers an innovative assessment of how well an electricity producer or consumer interacts with intermittent electricity supply, electricity markets, and other electricity demand in the energy system.

intermittency-friendliness : The coefficient is the statistical correlation between the energy-economy system's net electricity demand (electricity demand minus intermittent electricity supply) and the energy option's net electricity exchange with the energy-economy's electricity market. The intermittency-friendliness coefficient ranges of -1 to 1, and represents the "goodness" of an energy options's ability to support the intermittent renewables in the energy-economy system. Read the paper.

intermittency-volume : The coefficient is the consumption of electricity in market range below average electricity price, or the share of electricity consumption in below-average range market range to total electricity consumption.

User-defined uncertainties may be specified to allow for extensive Monte Carlo risk analyses and a subsequent statistical representation of results.

COMPOSE represents a vision that techno-economic rationality-driven platforms for social interaction may aid in reaching a tangible basis for discussing real conflicts, identifying winners and losers. The mission is for COMPOSE to combine the strength of operational simulation models with the strength of energy system scenario models in order to arrive at a modelling framework that supports an increasingly realistic and qualified comparative assessment of sustainable energy options.
