Integrated Energy Multi-Objective Operation Optimization

The Integrated Energy System (IES) offers a new approach to the energy dilemma. It introduces demand-side response into the Regional Integrated Energy System (RIES) and proposes an operational optimization model considering Integrated Demand Side Response (IDSR) in the framework of RIES. First of all, the typical cold\thermal\electric RIES is used as a framework to establish the multi-energy flow model of RIES based on the energy flow relationships among energy production, conversion and consumption. Then, from the perspective of energy transfer, the potential to enhance renewable energy consumption by carrying out RIES to transfer the system energy flow is analyzed. Finally, the RIES operation optimization model considering IDSR is established with the goal of the economy of system operation, considering the system energy balance and the operating constraints of each energy device, and the solution algorithm is designed. Taking the RIES in a certain region as an example, the proposed method and model were verified computationally, and the results showed that IDR can effectively improve system economics and increase the level of renewable energy consumption
