Research on urban energy Internet planning based on fuzzy comprehensive method

With the continuous development of China’s economy, the process of urbanisation and industrialisation has been accelerating, and coupled with the emergence of new energy, China’s urban energy consumption has undergone huge transformation. The urban energy Internet (UEI) is an important part of the country’s ‘carbon peak and carbon neutrality’, and it is also one of the key tasks in the planning, construction and operation of the power grid transformation. The traditional grid-side planning model relies on a single deterministic planning method, and there is less consideration for new influencing factors, which has been difficult to meet the energy demand in the context of the energy Internet. In this paper, research on UEI planning based on the fuzzy synthesis method is proposed. First, the basic architectural model of UEI is constructed. At the same time, the impact of distributed generation, energy storage, demand response, communication and other key technologies on the planning of active distribution networks in the distribution network planning under the UEI is analysed. Then, a fuzzy comprehensive method is proposed to calculate the weight of UEI planning. Finally, the planning and research of UEI prospects from the aspects of equipment form, system planning, operation control, business model and collaborative development are discussed.
