“…The value of the k th rule, r k (i, v, t, c), is calculated using instantaneous measures of current flow, i, voltage profile, v, time, t, and command, c, while the calculation of the k th resulting proposition, P k (μ P ), uses the resulting membership functions, μ P . Both values are used by the fuzzy controller in the defuzzification procedure given by (4).…”

“…2016.2518128 In the literature, different ways of implementing self-healing networks are described in [2] and [3], which also propose a hybrid architecture by combining centralized and distributed intelligence. Smart switching devices, communication systems and automatic restoration logic synthesize the hybrid nature of self-healing, and they are the successful keys of many distribution network projects, as assessed by [4]. In this paper, the keys to successful self-healing are followed using the technique of distributed artificial intelligence (DAI) to combine adaptive protection schemes with automatic restoration algorithms.…”

The increase in information and communication technologies in the electric power system has led the distribution network to a new evolutionary stage known as a smart grid. In this scenario, automatic local switching plans based on an understanding of the network topology and load behavior allow the implementation of self-healing strategies. Self-healing aims at the minimization of the number of switching operations within the shortest time interval to restore the maximum load affected by a fault and to preserve distribution network operation limits. In this paper, multiagent system concepts are employed to develop a self-healing strategy, where all switching local agents have some awareness regarding the current network state and work cooperatively to reach the global purpose of distribution network automatic restoration.

A Real-Time Monitoring Platform for Distributed Energy Resources in a Microgrid—Pilot Study in Oman

et al. 2021

This article presents the development of a platform for real-time monitoring of multi-microgrids. A small-scale platform has been developed and implemented as a prototype, which takes data from various types of devices located at a distance from each other. The monitoring platform is interoperable, as it allows several protocols to coexist. While the developed prototype is tested on small-scale distributed energy resources (DERs), it is done in a way to extend the concept for monitoring several microgrids in real scales. Monitoring strategies were developed for DERs by making a customized two-way communication channel between the microgrids and the monitoring center using a long-range bridged wireless local area network (WLAN). In addition, an informative and easy-to-use software dashboard was developed. The dashboard shows real-time information and measurements from the DERs—providing the user with a holistic view of the status of the DERs. The proposed system is scalable, modular, facilitates the interoperability of various types of inverters, and communicates data over a secure communication channel. All these features along with its relatively low cost make the developed real-time monitoring platform very useful for online monitoring of smart microgrids.

Detection and Prevention of Unintentional Formation of Loops in Self-Healing Power Systems and Microgrids

Self-healing or self-assembling power systems that rely on local measurements for decision making can provide significant resilience benefits, but they also must include safeguards that prevent the system from self-assembling into an undesirable configuration.One potential undesirable configuration would be the formation of closed loops for which the system was not designed, a situation that can arise any time that two intentional-island systems can be connected in more than one place, e.g. if tie-line breakers are included in the selfassembling system. This paper discusses the unintentional loop formation problem in self-assembling systems and presents a method for mitigating it. This method involves calculating the correlation or the mean absolute error (MAE) between the two local frequency measurements made on either side of a line relay. The correlation and MAE between these frequencies changes significantly between the loop and non-loop cases, and this difference can be used for loop detection. This paper presents and explains the method in detail, presents evidence that the method's underlying assumptions are valid, and demonstrates in PSCAD two implementations of the method.The paper concludes with a discussion of the strengths and weaknesses of the proposed method.
