“…The authors [12] confirm the need to study the problem of locating faults in EDS with DG, with new methods and with the combination of traditional methods. Similarly, the authors [13] indicate the importance of conducting investigations in locating faults in EDS with parallel approaches, i.e. combining different methods.…”

The exact location of faults in the electrical distribution systems is a problem that affects not only the users, but also the companies providing the electric service. With greater time invested in this period, the losses due to unbilled energy and inconvenience to users increases, thus decreasing the quality of service. One of the causes of the growth in time is the misunderstanding that might exist in the localization systems that act under the presence of distributed generation sources in the distribution networks. In this sense, the present research develops an intelligent diagnosis of faults in distribution systems with distributed generation. Three stages are defined: Identification of the type of fault, the location of the zone, and the exact point of fault. A mixed method based on artificial intelligence and mathematical algorithms is applied. Eleven different types of faults that can occur in a distribution system are considered with six different values of fault resistances ranging from 5 to 30. The errors found are less than 2% in the location of the fault point with robustness to variations in the load and the penetration of distributed generation.

Abstract. This paper proposes a new algorithm for optimum self-healing restoration of a smartmicrogrid operating in islanded mode of operation. The objective of the proposed algorithm is to optimize the topological structure of the islanded microgrid system (IMG) via: (1) maximizing the served load after the fault isolation; and (2) minimizing the switching operation costs. The proposed algorithm takes into consideration the system operational constraints in all operating conditions. The new algorithm accounts for droop controlled IMG special operational characteristics. The problem is formulated as a multiobjective optimization problem and solved using Ant Colony Optimization Algorithm. The proposed algorithm has been implemented in MATLAB environment and several case studies have been carried to test its effectiveness.

“…Presently, there is not much work on combining two detection schemes (hybrid-detection scheme) to fit it into a single system. Current works that is related to hybrid-detection schemes are mostly on fuzzy logic and data-driven techniques, such as ANN [178,179] or GA [180]. Through an in-depth computation and analysis of the detection scheme, it will contribute to a faster computational process and achieve a better optimization in the classification of fault and intermittency, variation of the controller's parameter, and a faster clearance time of power compensation devices.…”

Distributed Generation: A Review on Current Energy Status, Grid-Interconnected PQ Issues, and Implementation Constraints of DG in Malaysia

Electric supply is listed as one of the basic amenities of sustainable development in Malaysia. Under this key contributing factor, the sustainable development goal aims to ensure universal access to an affordable, clean, and reliable energy service. To support the generation capacity in years to come, distributed generation is conceptualized through stages upon its implementation in the power system network. However, the rapid establishment growth of distributed generation technology in Malaysia will invoke power quality problems in the current power system network. In order to prevent this, the current government is committed to embark on the development of renewable technologies with the assurance of maintaining the quality of power delivered to consumers. Therefore, this research paper will focus on the review of the energy prospect of both fossil fuel and renewable energy generation in Malaysia and other countries, followed by power quality issues and compensation device under a high renewable penetration distribution network. The issues and challenges of distributed generation are presented, with a comprehensive discussion and insightful recommendation on future work of the distributed generation. In accordance with the addressed highlights in this paper, it would serve as the criterion on upcoming revolution of distributed generation integrated along with the traditional network in Malaysia.
