Embodiment

[0128] This embodiment is a comprehensive energy system planning method that takes into account the characteristics of the natural gas pipeline network and the heat pipeline network, which includes the following steps:

[0129] Step 1. Build the energy center equipment model

[0130] The structure of building the energy center is as follows: figure 1 As shown, including multi-energy flow coupling devices and energy storage devices. The energy center is abstracted as an input-output dual-port network model. In the model, various energy flows are input and output from two ports respectively. The input and output ends of multi-energy flow coupling devices and energy storage devices can be regarded as converge to the same point.

[0131] 1) Multi-energy flow coupling equipment

[0132] The multi-energy flow coupling equipment inside the energy center plays the role of an energy converter, and through its internal electricity, gas, and heat multi-energy flows complement each oth...

Description

technical field [0001] The invention relates to the field of electric power system optimization, in particular to a comprehensive energy system optimization method considering the characteristics of natural gas pipeline network and thermal power pipeline network. Background technique [0002] The increasingly severe situation of energy sustainable development has prompted countries to break the existing mode of separate planning and independent operation of each energy system, and carry out research on the comprehensive utilization of multi-energy flows. The coordination and cooperation of multiple energy systems in the stages of planning, design, construction, and operation can promote the complementarity of multiple energy flows, promote the consumption of renewable energy, improve the overall efficiency of energy utilization, and enhance the flexibility of the energy system. The energy center abstracts the multi-energy flow coupling devices and energy storage devices in t...
