Abstract
Power system restoration has attracted more attention and made great progress recently. Research progress of the power system restoration from 2006 to 2016 is reviewed in this paper, including black-start, network reconfiguration and load restoration. Some emerging methods and key techniques are also discussed in the context of the integration of variable renewable energy and development of the smart grid. There is a long way to go to achieve automatic self-healing in bulk power systems because of its extreme complexity. However, rapidly developing artificial intelligence technology will eventually enable the step-by-step dynamic decision-making based on the situation awareness of supervisory control and data acquisition systems (SCADA) and wide area measurement systems (WAMS) in the near future.
Highlights
The modern power system is pushed close to critical operating limits in the market environment
This paper presents a review of the last decade of research, covering the areas of blackstart, network reconfiguration, load restoration, and emerging technologies from the year of 2006, applying to transmission system restoration; distribution system restoration [16] is beyond this paper’s focus
Ref. [33] presents a novel sectionalization method based on the wide area measurement system (WAMS) for the build-up strategy in power system restoration
Summary
The modern power system is pushed close to critical operating limits in the market environment. Power system restoration is a multi-objective, multi-stage, multi-variable and multi-constraint optimization issue, and is full of non-linearity and uncertainty. It can be described as a typical semi-structured decision-making and it is difficult to obtain a complete solution [4]. Power system restoration is still a very active and hot research area up to now To analyze it effectively, the three stages of black-start, network reconfiguration and load restoration are considered. This paper presents a review of the last decade of research, covering the areas of blackstart, network reconfiguration, load restoration, and emerging technologies from the year of 2006, applying to transmission system restoration; distribution system restoration [16] is beyond this paper’s focus
