How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Having Distributed Generators (DG), which are driven by renewable energy sources (RES) such as solar, wind and hydro, and biomass arises social, economic, and environmental issues and changes the conventional power systems to be more eco-friendly. However high penetration of DGs into low voltage (LV) distribution networks can cause overvoltage and thermal overloading problems and negatively affect the protection systems. Here the critical role of the term hosting capacity (HC) comes. HC is the capacity that indicates how much RES generation can be integrated into power networks, it is essential to evaluate HC and figure out ways to increase it. There are many HC enhancement techniques, one of them is using electrical energy storage systems (ESS) in power systems. This paper discusses the impacts of ESSs on the IEEE-13 bus system. The paper provides a description of the case when a modern optimization method was applied for HC enhancement using energy storages to minimize overvoltage in LV power systems.
