Abstract:

This paper designs a functional framework for multi-time scale optimal dispatch modules of multi-energy flow system. Practical technologies are proposed such as the dispatch decision considering users’ demand response of multi-energy and the energy storage dispatch decision considering multiple types of practical constraints. A multi-energy park optimal dispatch system is developed, which supports multiple energy combination scenarios including cold, heat, electricity, and gas. It fully exploits the multi-time scale adjustment capabilities of the load side, cooling/heating networks, and the energy storage resource to improve the dispatch flexibility and economy. This dispatch system has been operating in actual parks in several cities. Based on the online optimization results in two actual parks, the effect and adaptability of the optimal dispatch system are analyzed and verified.
