Optimized Operation of Power Systems with Consideration of Stability Aspects

Increasing electrification and remote renewable integration force power systems to operate near operational limits, often necessitating redispatch. However, high loading can compromise voltage stability even when static constraints are met. This paper proposes a Voltage Stability Constrained Optimal Power Flow (VSC-OPF...

ANALYSIS OF MODELS FOR ESTIMATING ELECTRICITY LOSSES IN DISTRIBUTION NETWORKS

The design of renewable energy sources and their connection to the electrical grids at different voltage levels leads to changes in the mode parameters of the grid. Electrical energy losses are of both technical and economic interest. The report examines the most commonly used models for estimating electricity losses i...

RISK ASSESSMENT OF NORMAL OPERATION VIOLATIONS AND CASCADING FAILURES IN POWER SYSTEMS

A comprehensive operational disruption and cascading failure risk assessment model for electrical equipment in power systems has been developed. The proposed model integrates a hierarchical structure of risk factors, probabilistic-statistical modeling, and fuzzy logic. This enables accounting for incomplete baseline in...

Evaluation of reliability indicators of microgrid decentralized sources based on statistical data

Numerous bombings of energy facilities by the Russian aggressor indicate that the centralized power supply system cannot meet the requirements of high-tech equipment for reliable power supply and the quality of electric energy. Power outages and significant electricity undersupply force us to look for decentralized pow...

Research on Key Indicators and Evaluation Methods for Flexible Energy Use in Building Electrification

Building electrification is critical to achieving zero-carbon goals. This paper reviews the technical pathways and evaluation metrics for building electrification, focusing on flexibility assessment under the PV-S-DC-F paradigm. It establishes a multi-dimensional indicator system and evaluation methodology that include...
