Abstract

The invention discloses a demand side response scheduling method under electric-gas-thermal multi-energy flow coupling, and belongs to the technical field of power system operation and control with multiple energy forms. The user on the demand side is a commercial building user installed with a distributed cogeneration unit. The method provided by the invention fully utilizes the flexibility of the user load in the multi-energy flow coupling environment, taps the user's demand side response potential, and transforms the user's energy demand which is conventionally fixed into a function of energy price. By using the user demand side response, the constraint conditions for operating the multi-energy flow coupling system are relaxed, thereby improving the operational flexibility of the multi-energy flow coupling system, and further improving the system operation efficiency and reducing the energy consumption. At the same time, the renewable energy with volatility may be better absorbed.
