Welcome from the IEEE PES ISGT Europe 2020 General Chairs
No full textWelcome from the IEEE PES ISGT Europe 2020 General Chairs On behalf of the Organizing Committee we are very pleased to welcome you to the 10th IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe) Conference organized by the Delft University of Technology, the Netherlands, which for more than 175 years has been one of the most prestigious public institutions both at an international and national level in education, research, technological transfer and services in all sectors of engineering. The IEEE-PES ISGT-Europe 2020 conference will stress the need for viewing the role of smart grids in future energy systems as part of the designing, managing and operating qualitatively new complex socio-technical systems. From a technical perspective, solutions to the limited ability to predict stochastic generation and demand can be found in novel technologies such as integrated communications, advanced sensing & measurement technologies, advanced control methods, improved interfaces and decision support. From an economic and regulatory perspective, the challenge is to innovate and deploy new technologies within new business models and market designs, so that the objectives to contribute significantly to a sustainable world will be met. This is the first ISGT conference that is conducted in a virtual fashion. This is a challenge but also an opportunity. Although we would have preferred to welcome the ISGT community in the beautiful city of the Hague located in South-Holland, we are happy to host you virtually this time. We kept the classical format of a conference with regards to timing and content, and tried to replicate the interactive elements such as discussions or social interaction with on-line tools. Conferences are - besides learning the newest trends and developments - for meeting peers and networking after all. A clearly positive aspect of virtual conferences such as this one are reduced costs, both in conference organization (and in attendee fees ) and travel. Still, we hope that we will meet soon again face to face and enjoy a few days together. We would like to thank all the conference sponsors and everyone that supported us in setting this IEEE PES ISGT-Europe 2020 up, from IEEE PES, the Technical Review Committee to the local team at TU Delft and wish everyone a fruitful and engaging conference. We look forward to meeting you virtually at the 10th IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe) Conference."Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public."Energie and IndustrieIntelligent Electrical Power Grid
Increasing Distributed Generation Penetration using Soft Normally-Open Points
No full textThis paper considers the effects of various voltage control solutions on facilitating an increase in allowable levels of distributed generation installation before voltage violations occur. In particular, the voltage control solution that is focused on is the implementation of `soft' normally-open points (SNOPs), a term which refers to power electronic devices installed in place of a normally-open point in a medium-voltage distribution network which allows for control of real and reactive power flows between each end point of its installation sites. While other benefits of SNOP installation are discussed, the intent of this paper is to determine whether SNOPs are a viable alternative to other voltage control strategies for this particular application. As such, the SNOPs ability to affect the voltage profile along feeders within a distribution system is focused on with other voltage control options used for comparative purposes. Results from studies on multiple network models with varying topologies are presented and a case study which considers economic benefits of increasing feasible DG penetration is also given
BCIT integrated grid laboratory planning framework
No full textThis paper presents a planning framework for an educational training facility designed to incorporate exposure to equipment and scenarios seen in modern power systems, such as islanded microgrids, distributed renewable generation, and new information and communications technologies. The overall architecture is geared towards addressing skills and training gaps in undergraduate “power systems” education. The design principles make this laboratory safe, robust, scalable, modular, and expandable and can therefore also be considered for transport to remote sites for training or demonstration purposes. The framework is based on development and implementation of such a facility at the British Columbia Institute of Technology (BCIT) in the Vancouver area of Canada. It is the goal of the author to allow other institutes to reduce overall implementation time and to share and collaborate on educational materials and pedagogical results. The paper concludes with the presentation of a cost function which ranks, according to the author and BCIT's planning experience, the relative costs and benefits for such a facility in comparison with other possible approaches

Possible orthotic solutions of Pes equinovarus congenitus
No full textAuthor: Petra Michalová Title: Possible orthotic solutions of Pes equinovarus congenitus Objective: The aim of this thesis is to point out and summarize the available options for solving the issue of Pes equinovarus congenitus. This thesis should also out provide vital information regarding the functional principles and technical composition of equipment and assess the influence of individual types of correction braces and create a basic overview of the relevant subject. The work is focused on the influence of knee-ankle-foot orthosis (KAFO) and ankle- foot orthosis (AFO) orthoses in one-sided congenital malformation of Pes equinovarus congenitus demonstrated on one case report. Methods: A proband at the age of about 1 with diagnosis of unilateral congenital malformation of the right lower limb (pes equinovarus congenitus) was involved. The proband was measured accordingly to provide specific data for the production of orthoses and then the subsequent production of three variants of orthosis suitable in the specific case of the solved proband took place. Results: The KAFO brace was proved to be the most efficient choice in this particular case. Keywords: pes equinovarus congenitus, congenital defect, lower limb deformity, orthotics, orthosis, KAFO, AF

The relationship between pes planus and venous insufficiency
No full textIntroduction The presence of pes planus may be responsible for the disorder of venous return during ambulation. Our aim in this study is to reveal that the risk of venous insufficiency may be increased in patients with pes planus. Methods A total of 59 patients with 29 bilateral pes planus and 30 normal arches included in the study. Djian Annonier angle measurement, bilateral lower extremity venous Doppler ultrasonography (USG), foot function index (AFI), Comprehensive Classification System for Chronic Venous Disorders (CEAP) clinical scoring and Short Form-36 (SF-36) was evaluated. Results There was a statistically significant difference in AFI total, AFI pain, AFI disability and AFI activity limitation scores, bilateral lower extremity doppler USG and CEAP clinical scores in the patient group compared to the control group. Conclusion These findings suggest that there may be a relationship between pes planus and venous insufficiency. However, large-scale studies with more patient involvement are needed.Kirikkale University Scientific Research Unit [2019/151]The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This project was funded by Kirikkale University Scientific Research Unit under grant no of 2019/151
