A study on integrated control of home-cogeneration systems for contributions to power system operations

In deregulated power systems, it is very important to make electricity demand more flexible in order to secure market-based system operation from power system operator's point of view. Also, as one of energy conservation technologies in Japanese residential houses, home-cogeneration systems such as gas engine-type and polymer electrolyte fuel cell-type (PEFC) is highly expected because exhausted heat of gas-engine or PEFC can be utilized for hot water demand. This paper assumes a new cooperation framework between cogeneration's owners and power system operator in order to attain more secure power system operation. In the cooperation framework, from cogeneration owner's point of view, the authors evaluate an influence of the integrated control of gas engine-type cogeneration systems on economic factor and energy conservation for cogeneration's owner.
