Problems solved by technology

[0004] The above studies provide a strong basis for the optimal dispatch of multi-energy systems with generalized energy storage, but there are still the following limitations and deficiencies: On the one hand, most of the current multi-energy system optimization models only consider power flexible loads as part of generalized energy storage. Less consideration is given to the contribution of thermal load regulation capacity to generalized energy storage; on the other hand, the current research is still insufficient to study the comprehensive regulation characteristics of power storage and heat storage devices, and less consideration is given to the system's electricity-to-heat conversion characteristics
