Electric energy storage in industrial parks

What is energy storage and Energy Internet?

In traditional power system, energy storage devices can stabilize the fluctuating output of renewable energy with high construction and operation costs . At the same time, the energy internet, which takes an integrated energy system (IES) as a physical network, is gradually promoted.

What EVs are in the Industrial Park?

The EVs in the industrial park include transport vehicles, official vehicles and private vehicles. The vehicle parameters and probability distribution of parking conditions (time variable definition domain is [0,96]) are shown in Table 2.

What type of heat is used in industrial parks?

In industrial parks, high-grade heat is preferentially used for gas turbines to generate electricity. Middle-grade heat is used to supply the energy for industrial steam loads, hot water loads or as a heat source for absorption chillers. Low-grade heat is used as a heat source for direct heating and absorption chillers [18 ]. 2.2.

How many gas turbines are there in the Industrial Park?

There are 3 gas turbines in the industrial park. The electricity purchasing price (the time-of-use price is adopted for the electrical power purchase price and electrical power sale price at time t is set at 0.8 times the electrical power purchase price at time t ), the natural gas price, and parameters of main devices are shown in Table 3.

What are the constraints of steam loads in industrial parks?

Constraints of steam loads There are steam loads in industrial parks. Middle-grade heat is used as the heat source to complete productive tasks. The steam load can be equipped with steam recovery devices to convert waste steam into low-grade heat.

What is a traditional energy system?

Mode 1: Traditional energy system uses a distribution network for power supply, electric boilers, gas boilers for heating and electric coolers, absorption chillers for cooling. The ACLs are described by typical load curves [5 ].
