Smart Distribution Network Situation Awareness for High-Quality Operation and Maintenance: A Brief Review

Abstract

In order to meet the requirements of high-tech enterprises for high power quality, high-quality operation and maintenance (O&M) in smart distribution networks (SDN) is becoming increasingly important. As a significant element in enhancing the high-quality O&M of SDN, situation awareness (SA) began to excite the significant interest of scholars and managers, especially after the integration of intermittent renewable energy into SDN. Specific to high-quality O&M, the paper decomposes SA into three stages: detection, comprehension, and projection. In this paper, the state-of-the-art knowledge of SND SA is discussed, a review of critical technologies is presented, and a five-layer visualization framework of the SDN SA is constructed. SA detection aims to improve the SDN observability, SA comprehension is associated with the SDN operating status, and SA projection pertains to the analysis of the future SDN situation. The paper can provide researchers and utility engineers with insights into the technical achievements, barriers, and future research directions of SDN SA.

Optimal Operation of Distributed Generations in Four-Wire Unbalanced Distribution Systems considering Different Models of Loads

“…Te optimization work contains objective functions [19][20][21][22][23][24][25][26][27] and constraints [28][29][30][31][32][33][34][35][36]. Also, to apply optimization to the distribution network, smart technologies [37][38][39][40][41] and telecommunications equipment [42][43][44][45] should be used in the network. In the objective function of the proposed problem, the minimization of the voltage deviation from the desired value and the minimization of the distribution network losses are expressed, respectively, to achieve the goals of improving the network voltage profle and reducing losses.…”

Low-carbon transition toward green recovery: policy framework after COVID-19

“…Green money, often known as sustainable or climate financing, has many meanings. Green finance refers to providing financial support for projects with positive effects on the ecosystem (Ge et al 2022 ). Alternatively, “climate finance” refers to funds explicitly allocated for initiatives that mitigate global warming.…”

Attainment of Zero Emission Targets by Transition Towards sustainable development of value of creative products

“…According to the World Energy Outlook, 2030(Zang et al, 2022, energy power plants account for more than 70% of global energy consumption. Authorities have stepped up their sustainability responsibilities because of the effects of climate change (Ge et al, 2022). And over 800 million individuals will be affected by the "environmental movement" by March 2019, when 1046 authorities in 30 states proclaim it (Iqbal et al, 2019).…”

“…The primary goal of every economic system is to raise GDP without sacrificing emissions standards. Many studies (Walker, 2020;Ge et al, 2022) show a direct relationship between economic growth and sustainable energy use. Studies have shown that information and communication technology can help to minimize energy consumption in different areas, such as construction, storage, and transportation, by offering practical technologies (Wang H. et al, 2021).…”
