User-side comprehensive energy system planning method and device based on IGDT model

Abstract

The invention provides a user-side comprehensive energy system planning method and device based on an IGDT model. The method comprises the following steps: inputting basic data; constructing a user-side comprehensive energy system planning model by considering the economic cost, the environmental cost and the reliability cost in a user-side comprehensive energy system; constructing an IGDT optimization model, and constructing an IGDT-based user-side comprehensive energy system planning model by considering the uncertainty of renewable energy output and cold and hot electric load growth in theuser-side comprehensive energy system; and solving and outputting an IGDT-based user side comprehensive energy system planning result according to the basic data and the IGDT-based user side comprehensive energy system planning model. The technical scheme provided by the invention is more suitable for actual problems, has better theoretical research value and actual application value, effectivelyimproves the economy, reliability and stability of user-side comprehensive energy system planning, and has higher feasibility.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a user-side comprehensive energy system planning method and device based on an IGDT model. Background technique [0002] In order to actively promote the adjustment of energy structure, properly cope with the shortage of petrochemical energy and solidly promote environmental protection, in recent years, my country has begun to implement the energy development strategy of replacing coal with electricity and replacing coal with gas, which has made the connection between energy sources closer and closer, breaking the separation of various energy sources. The existing mode of planning and independent operation has gradually formed a comprehensive energy system in the park with coordinated operation of multiple systems such as power distribution and gas distribution, and multiple energy sources complementing each other. [0003] The economic and stable operation of the user-side in...

Problems solved by technology

For now, there are few studies on uncertainty planning in the expansion planning of integrated energy systems. At present, the planning model of user-side integrated energy systems focuses on the problems of energy production, type selection of conversion equipment, and capacity allocation. IGDT theory is applied to the user-side energy system planning problem, and there is no research on the instability of renewable energy output in the integrated energy system and the uncertainty of different types of load growth of cooling, heating and power.
