New energy storage for cross-regional power transmission

Is cross-regional power transmission feasible?

Especially in winter when the peak regulation pressure is huge, the peak-valley difference of two REPGs is reduced by 667–1242 MW and 2582–2740 MW, respectively. It is proved that the cross-regional power transmission of a WF-PSHP system is feasible.

How to solve long-distance cross-region power transmission problem?

In order to solve the problem of long-distance cross-region power transmission, China vigorously develops ultra-high voltage (UHV) power transmission technology to solve the contradiction between regional supply and demand, which is effective to improve the integration of RE ( Liu et al., 2018 ).

How does cost competition affect the cross-regional energy transportation form preference?

Moreover, the changes of cost competition between power transmission and hydrogen transportation will influence the cross-regional energy transportation form preference as well as the VRE power installation in each region to achieve an optimized deployment.

Is cross-regional integrated transmission of wind power and pshps effective?

Thus, using the cross-regional integrated transmission of wind power and PSHPs is an effective measure for the large-scale accommodation of wind power. In recent years, there have been many studies on the joint operation of WFs and PSHPs.

Is the cross-regional power transmission of a WF-PSHP system feasible?

It is proved that the cross-regional power transmission of a WF-PSHP system is feasible. The allocation ratio of energy production has little influence on the reduction of peak-valley difference, but the weight of the REPGs in the operation process has a great impact.

How does cc utilization affect cross-region power generation?

The improvement of CC utilization will squeeze non-fossil energy power generation in some regions, and weaken cross-region exchange electricity. As a result, multiple trans regional power transmission channels are no longer expanded ( Fig. 3 ). Fig. 3.
