How is the pipe network layout of energy station solved?

Thirdly, the pipe network layout of energy station is solved based on energy supply area division results of energy stations in Part 5. Fourthly, combined with the pipe network layout scheme, the energy station site selection is optimized and the energy supply area of energy station is divided again in Part 6.

Why is pipe sharing important in energy pipe network layout?

Due to the common phenomenon of pipe sharing in energy pipe network, the pipe flow will depend on the load connected with the pipe. Therefore, the energy supply route between each load within the energy supply area and the energy station should be considered in the pipe network layout.

What is a typical integrated energy system?

A typical integrated energy system consists of a natural gas sys-tem, a thermal system and a power system, whose structure is as shown as the first block in Figure 1. In the first block, the combined heat and power (CHP) unit is the core device that will achieve interaction among the three subsystems of the IES.

How to ensure the energy pipe network economic construction?

In order to ensure the energy pipe network economic construction, the pipe should be laid on the road within the energy supply area as far as possible, circuitous energy supply from the energy station to the load should be avoided, increase the pipe sharing between different loads to reduce the length of pipe construction.

How much energy is stored in a gas linepack?

The amount of energy stored in the gas linepack is equivalent to that provided from three 100 m3 LNG tanks whose capital expenditure is around $1 .3 105. × Similarly, the thermal inertia of heating network and buildings is equivalent to the heat stor-age tanks installed in heating system.

Can a nonlinear optimization model improve pipeline network expansion?

Kabirian and Hemmati proposed a nonlinear optimization model to obtain the pipeline network expansion in multi-period pipeline network planning with least discounted operating and capital costs, considering the type, location, and installation schedule of pipelines and compressor stations.
