Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0018] A typical comprehensive energy system planning method, the system planning method includes:

[0019] Step 1: The integrated energy system coupling model, such as figure 2 shown. The coupled model shown includes the energy input (P 0 is the distributed energy input, P e is the electrical input, P g is the gas input), the intermediate energy conversion link, and the energy output (L e is the electrical output, L h is gas output, L 0 for distributed energy output) and energy storage devices (S 1 and S 2 ).

[0020] Step 1.1: List the coupling relationship between the input and output of the energy system:

[0021] L = C P (1)

[0022] In formula (1): L is the output, P is the input, a...

Abstract

The invention relates to a multi-source coupled integrated energy system planning method. The method comprises steps that 1), an integrated energy system coupling model is established, and the coupling relationship among cold/heat/electrical/gas energy forms is described through listing mathematics coupling matrixes; 2), regional present situation analysis is carried out; 3), regional energy demand prediction is carried out; 4), energy supply equipment output analysis is carried out; and 5), energy station site selection and capacity setting are carried out, energy station site selection is reasonably determined, an energy station optimization planning target function and a constraint condition establishment solving model are determined, and the optimal energy station configuration capacity is acquired through solving the model. The method is advantaged in that on the condition that cold/heat load demands can be satisfied, site selection and capacity setting of a wind turbine generatorsystem, a photovoltaic electrical station, a gas turbine set and a ground source heat pump set are optimized, and bases are provided for planning and operation of an integrated energy system.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy system planning, in particular to a multi-source coupling comprehensive energy system planning method. Background technique [0002] The generalized energy system includes subsystems such as power system, heating system, cooling system and natural gas system. Under the traditional energy supply mode, different systems are planned, operated and managed independently, which has resulted in the redundant construction of some energy facilities, inhibiting the improvement of energy use efficiency and the consumption of renewable energy. [0003] The integrated energy system is an integrated energy network with multiple energy interactions, and it is an important form of development in the energy field. The integrated energy system can significantly improve energy utilization efficiency and local consumption capacity of distributed renewable energy through comprehensive planning, coordinat...
