Criteria and Indicators for Evaluating the Effectiveness of Digital Transformation
Full text linkThis article examines the criteria and indicators used to evaluate the effectiveness of digital transformation in energy enterprises. Emphasis is placed on both economic and technological aspects, as well as data management and service quality indicators. The study outlines a comprehensive framework based on theoretical approaches such as the neoclassical, institutional, and innovation-based views of effectiveness. A system of evaluation metrics—including ROI, NPV, automation levels, and consumer satisfaction—is presented, along with modern assessment methods such as the Balanced Scorecard (BSC), Analytic Hierarchy Process (AHP), and Data Envelopment Analysis (DEA). Practical applications are illustrated using statistical data from the digitalization initiatives of “National Electrical Networks of Uzbekistan” JSC. The results underscore the importance of integrated evaluation tools for effective strategic management in the context of energy sector digitalizatio
Justification of the design parameters of the combined device

Circulatory System Diseases And Issues In Their Classification
Full text linkThe circulatory system plays a critical role in maintaining the homeostasis of the body and ensuring general health, as it delivers nutrients, oxygen, and hormones to all parts of the body. However, various diseases that disrupt this complex system significantly affect individual well-being and public health. Conditions such as heart disease, hypertension, and vascular diseases are among the leading causes of morbidity and mortality worldwide. Despite their importance, the classification of circulatory system diseases remains a complex issue in the medical fiel
A Comprehensive Analysis Of Mppt Techniques For Photovoltaic Systems Under Partial Shading Conditions
Full text linkMaximizing power extraction from photovoltaic (PV) systems is crucial for improving efficiency, particularly under partial shading conditions (PSCs). The high cost and relatively low conversion efficiency of PV panels necessitate effective maximum power point tracking (MPPT) techniques to ensure operation at the maximum power point (MPP). This paper presents a comprehensive review of 11 MPPT methods reported in the literature, alongside recent advancements in hardware design methodologies. The MPPT techniques are classified into three categories—Classical, Intelligent, and Optimization-based—according to their underlying tracking algorithms. Under uniform irradiance, classical methods are generally preferred due to the presence of a single peak in the power–voltage (P–V) curve. However, under PSCs, the P–V curve exhibits multiple peaks, including one global MPP (GMPP) and several local MPPs (LMPPs). As a result, intelligent and optimization-based techniques have emerged to accurately identify the GMPP among all local peaks. Each MPPT technique is critically analyzed in terms of sensor requirements, hardware implementation complexity, performance under PSCs, cost, tracking speed, and tracking efficiency. This study consolidates recent advancements and highlights potential research directions to support further development in the field
Assessment of Power Quality Indicators in Electrical Networks Connected to Distributed Generation Sources
Full text linkThis article is devoted to the assessment of power quality indicators in electrical networks connected to distributed generation sources. It discusses key parameters necessary to ensure power quality, such as voltage stability, frequency control, power flows, and harmonics. The article notes that distributed generators can inject power from various sources into the grid, which may lead to changes in network parameters. Therefore, it emphasizes the need for continuous monitoring of network quality. The article also presents the permissible normative values for voltage and current harmonic components. It concludes that, for reliable and stable operation of the power network, the output parameters of distributed generators must remain within established limit
