Power systems have been going through a barrage of transformations due to the recent developments in the field, such as deregulation and restructuring of the electric power supply chain, the proliferation of distributed generation (DG), and advancements in information and communications technologies. These have significantly impacted the approach to the planning, design, and operation of active distribution networks or systems. Due to this constant change, the system has become more complex to plan, maintain, and control. In this paper, the benefits and challenges of active distribution systems relative to traditional passive and active distribution systems are evaluated and investigated while the management and operational characteristics of demand-side resources in active distribution systems (ADS) are studied. In a typical ADS, there exist several vulnerabilities and threats that eventually pose a challenge in the control and automation of substations. These vulnerabilities and threats are reviewed, and potential mitigation measures are suggested. Also in this paper, the communication technologies and their implementation in terms of control and automation capabilities in active distribution networks are also studied. From this work, it is concluded that communication technologies play an integral role in the realization of more active distribution networks and that the Internet of Energy (IoE) is a major player in ADS in the reduction of faults due to human error, fast responses, and improving the stability of power supply. Cyber threats are also and will still be a continuous challenge in smart metering technologies and in substation automation systems (SAS), which will require frequent evaluation and mitigation measures so as not to prevent the power supply system from collapsing.

“…As far as the electricity infrastructure is concerned, once it is produced in power plants, exploiting the chosen energy source (fossil fuel or renewable energy sources) and supplied through power lines at high voltage, being able to travel even great distances through the use of auto-transmitters it switches to medium and low voltage (the form in which it is supplied to users) as the network branches out over the territory thanks to the intervention of energy supply companies [105][106][107][108][109][110][111][112][113][114][115][116][117][118][119].…”

Supporting Cities towards Carbon Neutral Transition through Territorial Acupuncture

Since a solution towards carbon neutrality in already highly populated territories that does not profoundly alter the territories has not yet been found, territorial acupuncture, a new methodology presented in this paper, proposes a solution to this challenge and simultaneously helps to counter the dysfunctional dichotomy between large urban centres and small towns. The aim of this study is therefore to present this new concept and its operation. Hence, a phased study was carried out. Territorial acupuncture is the result of merging different theories and practices, such as Biourbanism, urban acupuncture, and energy community design. For Territorial Acupuncture, the territory is conceived as a single organism and, just like acupuncture in traditional Chinese medicine, punctual interventions (in this case, interconnected energy communities) would benefit the entire territory organism. To make the theory work properly, it will be necessary to carry out multi-scalar and multi-disciplinary analyses over the entire territory to identify the intervention points and then proceed to the design and interconnection of the individual district. Thus, Territorial Acupuncture provides a new approach to the resilience of densely populated territories, which, through punctual interventions on a district scale, benefits the entire territory by modifying energy, socio-economic, and environmental dynamics.

“…Control is used to regulate the power flow within the microgrid, handling voltage stability, power quality, and other issues to keep the electricity flowing. Data are related to the generation, transport, and aggregation of data from sensors and other sources spread throughout the microgrid [90,133,134].…”

Understanding Microgrid Sustainability: A Systemic and Comprehensive Review

2022

View full text Add to dashboard Cite

There is a growing research interest in studying microgrids as a way to overcome the lack of access to energy. These microgrids could be the key to global energy access because of their many advantages related to flexibility, efficiency, and reliability. Despite all these qualities, microgrids remain challenging to implement in a sustainable and resilient way without a clear consensus on what causes these failures. To this end, this work proposes a new paradigm to make a multidisciplinary and comprehensive review of the operation of microgrids. By reconciling the different fields inherent to microgrids, this review enables the study of microgrids within a unified framework. Microgrids will be presented through energy, information, financial, and social fields to provide the necessary elements for their systemic understanding. Each field will be presented with its internal elements, architecture, and significant issues. By elaborating on this new vision of microgrids, this article hopes to open the way to a deeper understanding of their systemic operation and diagnose their long-term sustainability.
