• Feasibility Study on Demand Response by Cogeneration System (CGS) under Large-scale Integration of Renewable Resources

抄録

Cogeneration system (CGS) is expected to provide flexibility of energy system on the basis of its swift responsiveness of power output adjustment under large-scale integration of renewable energy, as well as to make multiple contributions in primary energy conservation, CO₂ mitigation and BCP (business continuity plan) enforcement. CGS serves as measure for electricity load shedding if CGS output increases by using the idled capacity, while CGS plays a role in electricity load extension if CGS output goes down and electricity is alternatively purchased from power grid. This paper investigates the potential of demand response (DR) by the utilization of CGS, composed of gas-engine and gas-turbine systems, nationwide in Japan and attempts to evaluate the implementable possibility of the CGS-based DR by an optimal power generation mix model, highlighted by detailed geographical resolution derived from 352 nodes and 441 bulk power transmission lines with hourly temporal resolution through a year. The results suggest that the cost reduction of CGS promotes the introduction of electric power load-shedding and the massive integration of renewable increases the implementation of load extension by CGS-based DR.
