“…Separate result details were obtained from the analysis of both the minimum/maximum demand scenarios generated by the proposed system to provide a more comprehensive understanding of the problem for each power quality and efficiency analysis variable. Acquired results can be applied in design, development and implementation of systems in which energetic demands are crutial variables of feasibility [56].…”

This study proposes a novel technique of cooperative control for a distributed hybrid DC/AC Microgrid (MG) by designing a digital Infinite Impulse Response (IIR) filter-based Proportional-Resonant (PR) current controller. This controller adopts an Adaptive Neuro Fuzzy Inference System (ANFIS) trained by Particle Swarm Optimization (PSO) to control inverter output current while tracking Maximum Power Point (MPP). A hybrid ANFIS-PSO extracts maximum power from both inverter and boost converter-based solar Photovoltaics (PVs) systems quickly and with zero oscillation tracking. The proposed PR controller cancels harmonics while achieving high gain at the resonant frequency (grid frequency). The PR controller offers quick reference signal tracking, grid frequency drift adaptation, easy system design, and no steadystate error. Moreover, this investigation features a PR controller frequency-domain analysis. The proposed technique smooths voltage and improves steady-state and transient responses. Cooperative control is implemented on an IEEE 14-bus MG with distributed communication. The findings indicate that the proposed control technique can regulate MG voltage to obtain a more stable voltage profile. The adopted MG, made up of dispersed resources, is crucial for assessing power flow and quality indicators in a smart power grid. Finally, numerical simulation results are utilized to verify the recommended technique.

“…This positive relationship is more profound for firms that face low agency concerns, firms that have a higher level of customer awareness, firms that have more long-term institutional ownership or firms that do not face financial constraints. Mikulecký et al (2011) focused on Ambient environment and its properties and abilities. Accenture (2023) presented next point of view "Sustainability is the new digital".…”

Current non-financial reporting guidelines and new non-financial reporting directive are described and compared at the beginning of the article. The aim of the paper is to map and analyze non-financial and CSR reporting activities in the TOP Responsible Firms in reporting in the Czech Republic in 2022. The focus will be to the forms of reporting. The annual report, the individual CSR report and information at the www pages are the three basic reporting channels for publication. Additional criteria will be analysed in all three reporting options. The analysis showed that only four companies use all three channels for reporting. The best in the reporting are two commercial banks, Accenture Central Europe B.V. and ČEZ Group. They report about CSR in the annual reports, in special reports and on www pages. All of the analyzed companies report according to regulations in law and more detailed data.

“…An extension can also consist of connecting to automated data processing or analytical tools that are commonly used in other areas, e.g. reporting tools or ambient intelligence and smart environment methods and technologies (Mikulecký et al, 2011) or developing easily searchable and properly organized corporate web pages (Bartuskova & Soukal, 2016) presenting related information to all employees in the organization. However, this path of development is strongly associated with technological readiness and ICT investments (Svobodova & Hedvicakova, 2017).…”

Natural or man-made disasters affect organizations quite often. Similar events can be coped with to a certain extent as organizations have safety plans, protocols and emergency procedures. Their development and application are associated with the discipline of emergency management. Its task is to minimize or even eliminate damages or casualties related to the occurrence of hardly predictable catastrophes. The aim of this paper is to present a system dynamics model enabling decision support for managers during all four stages of emergency management, namely mitigation, preparedness, response and recovery.Based on the search in scientific databases and consequent content analysis, causal-loop and stock-and-flow diagrams were developed. The model consists of six modules. While the first one represents the source related to tsunami generation, the remaining five modules deal with objects of interest such as buildings, infrastructure, environment or people. The model represents a simple and still immature example that demonstrates how the system dynamics methodology can be utilized in this domain in practice.
