Problems solved by technology

However, the current demand response is mostly based on electrical loads, and few studies consider the regulation of heating / cooling loads, and do not make full use of the coupling relationship between energies to achieve efficient energy matching.

[0005] In addition, most of the current research on demand-side response uses time-of-use electricity price and incentive policy response to load peak-shaving and valley-filling, but does not consider the matching relationship with the energy supply strategy, especially the coupling of electricity and heat of the cogeneration unit on the energy supply side. The demand-side response based on time-of-use electricity prices and incentive policies can easily cause mismatches with energy supply strategies and affect system performance
