“…The next step will be implementation on a real “controlled” distribution network consisting of the test polygon of public SMART LED lighting on the campus of VSB (the Technical University of Ostrava) [ 135 , 146 , 147 ]. This polygon is used for comprehensive testing of LED lighting in terms of Power Quality [ 148 ], consumption, and extended functionalities (e.g., visible light communication [ 149 , 150 , 151 , 152 ], smart parking management [ 153 ], smart energy flow management [ 148 ], etcetera). The subject of ongoing research is primarily the impact of widespread mass deployment of smart technologies on the quality of electricity within the city distribution network.…”

The field of advanced digital signal processing methods is one of the fastest developing scientific and technical disciplines, and is important in the field of Shunt Active Power Filter control methods. Shunt active power filters are highly desirable to minimize losses due to the increase in the number of nonlinear loads (deformed power). Currently, there is rapid development in new adaptive, non-adaptive, and especially hybrid methods of digital signal processing. Nowadays, modern methods of digital signal processing maintain a key role in research and industrial applications. Many of the best practices that have been used to control shunt active power in industrial practice for decades are now being surpassed in favor of new progressive approaches. This systematic research review classifies the importance of using advanced signal processing methods in the field of shunt active power filter control methods and summarizes the extant harmonic extraction methods, from the conventional approach to new progressive methods using genetic algorithms, artificial intelligence, and machine learning. Synchronization techniques are described and compared as well.

“…Experimental results show that the Cell-Rtree index has higher spatial query efficiency and utilization rate in the virtual city application environment than traditional index methods such as Rtree and quadtree (Jiang et al, 2019). Soustek et al (2019) proposed a method to describe Harris corner direction features with three vectors. They introduced the feature description method used in Scale Invariant Feature Transform (SIFT) algorithm into feature point description.…”

Intelligent scene design schemes have become increasingly important with the development of digital media art and Augmented Reality (AR) technology. At present, the design of this scene is mostly used in urban planning. The development of AR technology makes the constructed scene more realistic and immersive while drawing virtual cities. This paper establishes a virtual city through intelligent scene and AR technology and conducts reasonable urban planning based on the collection of sunshine information. Firstly, the application of blockchain technology is introduced. Secondly, it describes the digital media art intelligent scene and AR technology. Finally, the sunshine information obtained from the intelligent scene is used to optimize the virtual city buildings. The experimental results show that: building groups based on the sunshine information identified by intelligent scene can increase the sunshine time of both residential and commercial building groups and reduce the optimization time, which greatly improves the building planning level of virtual cities. Additionally, the introduction of AR technology makes the virtual city more realistic. Therefore, this study has certain reference significance for planning virtual cities.

“…It follows from the above that the issue of network interference in modern street lighting is a very topical matter. In response to these problems, the BROADBAND LIGHT test polygon was built in the parking lot next to the Faculty of Electrical Engineering and Computer Science at the VSB-Technical University of Ostrava Campus [16,[19][20][21]. The test polygon allows testing of new street lighting technologies; measuring their impact on the power quality in various operating states [22]; and, in the future, also testing active filtration [23].…”

This study focuses on the design of a measuring system for monitoring the power quality within the SMART street lighting test polygon at university campuses with relation to testing an adaptive current control strategy for three-phase shunt active power filters. Unlike conventional street lighting, SMART elements are powered 24/7. Due to the electronic character of the power part of such mass appliances, there are increased problems with the power quality of the electric energy. Compared to the current concept of street lighting, there is a significant increase in the content of higher current harmonic components, which cause several problems in the distribution system. The test polygon contains 16 luminaires made by various manufacturers and mounted with various SMART components. Using the polygon control and monitoring system, dynamic load scenarios were selected. These scenarios tested the possibilities of different adaptive current control strategies for three-phase shunt active power filters to improve the power quality of electricity. This study focuses on three adaptive algorithms that respond to dynamic changes of current harmonics level in real-time. The possibility of active filter control was tested using FPGA, mainly due to the low latency of the filter control part.
