How much electricity does an industrial park need?

Among them, the maximum cooling load is 2933.78 kW, and the maximum heating load is 1439.52 kW. The electricity load required for the production of the industrial park is shown in Fig. 4 (b). As can be seen, the electricity load in summer and autumn is 20% higher than that in spring and winter.

Why are industrial parks difficult to maintain?

Industrial parks have a variety of forms of energy supply, which includes the combination of a variety of different energy sources . In addition, it is very challenging to maintain the operation and scheduling of the industrial park as it has a large energy load, complex coupling characteristics and a high energy peak–valley difference.

Do energy storage equipments affect the energy consumption of a park?

It is noticed that the involvement of energy storage equipments is more frequent in the park’s peak and valley periods of energy consumption. By participating in the adjustable load demand response during working hours, the park reduces the cooling load demand within a reasonable range.

What is an integrated energy system model?

6. Conclusions and prospects An integrated energy system model is established in this paper, which comprises many different types of demand response. The objective of this work is to include the calculation of the operation costs and the carbon emission of the park in typical days.

How to optimize parks with integrated energy systems?

In optimizing parks with integrated energy systems considering integrated demand response, the economic objective of the system operation optimization is usually considered; therefore, the multiple objectives are transformed into a single goal that has to be solved.

How does the energy storage system maintain the energy state?

During the period of 21–24 h, the energy load and energy price in the park continue to decline. Reaching a trough, the proportion of power grid to power purchase has increased, and all energy equipment contributes to maintaining load balance. In addition, the energy storage system also maintains its energy state through charging and discharging.
