“…• Replacing conventional reclosers with "Pulseclosers" provides a limitation in depth, duration and number of sags as it determines fault type (permanent or temporary) with low magnitude test current and prevents reclosing onto permanent faults [19].…”

Voltage sag is the most common power quality problem, which has significant consequences for industrial customers. In industrial facilities, microprocessors and semiconductor-based automated equipment is widely used. These devices are extremely vulnerable to deviations in supply voltage. Consequently, the voltage sag performance of industrial facilities needs to be assessed by measurement studies to determine root causes, characteristics and the size of the problem. In consultation with ÅF Consult Turkey, Trakya Electricity Distribution Company conducted an R&D project funded by the Turkish Energy Market Regulatory Authority to characterize and analyze voltage sag events in electrical distribution networks. In this study, power quality measurement with an IEC 61000-4-30 Class A monitoring device was performed in a textile facility in the Thrace region. The event records were evaluated using sag indices according to IEEE Std. 1564-2014 and voltage waveforms were analyzed. Furthermore, the root causes, the cost of voltage sag events and possible mitigation methods were explored.

Summary Wildfires are natural phenomena that play a crucial role in many forest and grassland ecosystems. Under favorable conditions, that is, extreme heat, availability of fuel, and high winds, they may spread beyond control and approach city limits. Power lines are vulnerable to wildfires in their vicinity, mainly because of increased conductor temperatures as a result of ambient temperature rising. This may lead to conductor annealing and/or increased sag. A violation of safety clearances of the lines could in turn lead to possible flashovers and onset of cascading failures. To address the situation, the operator may dynamically alter the ratings of the lines in the affected areas in order to reduce the flow of current through them, thereby assisting with conductor cooling. However, with reduced line capacities, the utility may not be able to supply all the loads from the main substation anymore, which may increase the risk of unserved load and load shedding. A solution is put forth in this paper that enables the system operator to dispatch distributed generators, demand responsive loads, and microgrids in order to supply loads under such emergency conditions. Because of the uncertain spread/severity of wildfires, the problem is stochastic in nature and is therefore modeled as two‐stage stochastic optimization. First‐stage variables determine the generation capacity to be purchased before the onset of the event, while second stage variables represent generation dispatch commands. The efficiency of the proposed solution is verified on a modified version of the Institute of Electrical and Electronics Engineers (IEEE) 123‐bus test system.

“…In [17], electric vehicles are treated as dispatchable DGs in the restoration process. S&C Electric Company developed a MAS-based commercial product, named as IntelliTEAM, and applied them in Canada and Britain [18], [19]. In Intel-liTEAM, the agent collects the capacity limits of all available backup feeders as well as their power-supply substations, selects the one with enough capacity as the new power supply feeder for the out-of-service sections.…”

A Multi-Agent-Based Self-Healing Framework Considering Fault Tolerance and Automatic Restoration for Distribution Networks

Increasing penetration of distributed generators (DGs) brings new challenges to the control and protection of distribution networks. This article proposes a control and protection framework based on Multi-agent System (MAS), in which situation awareness of zone agents plays an important role. The main protection is designed to locate and isolate faults based on the peer-to-peer communication among the zone agents. Fault-tolerant mechanisms, including self-inspection and backup protection, are developed to cope with the malfunction of individual MAS and local communication failure. An automatic parallel restoration scheme that doesn't require complete grid information is proposed to restore the power supply. Comprehensive simulation studies are carried out on a 71-bus distribution network with DGs using DIgSILENT, and the results have shown the effectiveness of the proposed self-healing framework.
