Abstract
The economy of distribution networks largely depends on the utilization rate of distribution network equipment. Most of the emerging intelligent power consumption technologies have a positive effect on equipment utilization and their use can save investment of distribution networks. In this paper, the influence of intelligent power consumption technologies on the utilization rate of distribution network equipment is reviewed. The evaluation methods and indexes are assessed first and then intelligent power consumption equipment with energy storage function, vehicle-to-grid (V2G) technology and time-of-use (TOU) tariff are reviewed respectively. It is concluded that these intelligent power consumption technologies and measures have great potential to improve utilization rate of distribution network equipment because of their effective improvement to power load. Meanwhile, recommendations on how to utilize these intelligent power consumption technologies to improve utilization rate of distribution network equipment are proposed.
Highlights
The utilization rate of distribution network equipment, which plays an essential role in power system economy, has received extensive attentions with the rapid development of smart grid [1]
V2G technology combined with demand side management (DSM) can be used to provide the reserve by Electric vehicle (EV) for distribution networks in the peak period, effectively save the cost related to increasing generator units, reduce the loss of generators and improve the utilization rate of distribution network equipment
6 Conclusion The utilization rate of distribution network equipment is closely related to the economy of distribution network construction
Summary
The utilization rate of distribution network equipment, which plays an essential role in power system economy, has received extensive attentions with the rapid development of smart grid [1]. 3.3 The influence on the utilization rate of distribution network equipment Applying electrical energy storage technology to industry and daily life through intelligent power consumption equipment can effectively improve the utilization rate of distribution network equipment. DSM and demand response (DR) as the two most important methods in intelligent power consumption [34], are applied to encourage consumers to participate in shifting peak load, and have a great effect on the improvement of the utilization rate of distribution network equipment. Combining the DSM with the intelligent power equipment with energy storage function in a right way can shift the load from the peak to the valley period of distribution networks, improve the load rate and decrease the capacity of the distribution transformers. Strengthening the DSM and promoting the electrical energy storage technology have important significance
