Abstract

The invention relates to an off-grid integrated energy system double-layer planning method. The method comprises the steps of: obtaining renewable energy typical day data, cold, heat and electric loadhistorical data, equipment parameters in an integrated energy system, operation parameters and operation conditions of the integrated energy system; constructing a mathematical model of each energy supply device in the comprehensive energy system; according to the structure of the comprehensive energy system, constructing the double-layer optimization model of the comprehensive energy system, enabling the upper-layer optimization model to plan the system equipment capacity with the minimum total cost of the off-grid integrated energy system as the target, and enabling the lower-layer optimization model to optimize the system operation state with the minimum system load shortage as the target; and solving the double-layer optimization model to obtain the optimal capacity configuration result of the integrated energy system. An electricity-to-gas conversion device is applied to off-grid integrated energy system planning, the electricity-gas coupling performance is improved, the system cost is reduced, and the economy of the system is improved.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy, in particular to a two-layer planning method for an off-grid comprehensive energy system. Background technique [0002] The microgrid composed of distributed power supply, energy storage device, energy conversion device and load has been widely used because of the flexibility of distributed power supply and high energy utilization rate. However, with the increasing depletion of energy and the gradual improvement of people's requirements for energy quality, the traditional micro-grid will no longer be applicable. The comprehensive energy system including combined cooling, heating and power can effectively solve the above problems. Compared with the traditional micro-grid, the integrated energy system integrates the combined cooling and heating system, which can meet the needs of users for cooling energy, heating energy and electric energy at the same time, and different forms of ener...
