The project will demonstrate how incorporating a diverse generation and storage portfolio allows an urban district energy system to improve its eficiency by at least 50% and increase its backup power by at least 40% with a return on investment of 10 years or less. The improvement will be evalu-ated against the baseline operations for two urban ...

Cogeneration or combined heat and power ( CHP) is the use of a heat engine [1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover ...

To solve these problems, localised energy storage systems have therefore often been proposed as a complementary technology to m-CHP [2], [3], [16]. M-CHP systems with high heat to power ratio are more suitable for domestic applications where the power demand is continuously much lower than the heating demand [1] .
