Abstract:

Проблема надійності електричних станцій, електричних підстанцій, повітряних та кабельних ліній електропередач, електричних мереж та систем – одна із першочергових проблем електроенергетики. В окремих електроенергетичних системах кількість аварій протягом одного року може сягати кількох десятків, а річне недовідпущення електричної енергії внаслідок таких аварій – кількох мільярдів кіловат-годин. Можливі наслідки від ненадійності стають такими суттєвими, що потрібно постійно вдосконалювати методи прогнозування розвитку, проектування, будівництва, монтажу та експлуатації енергетичних сист

With the growing popularity of Bring Your Own Device (BYOD), modern enterprise Wireless Local Area Networks (WLANs) deployments always consist of multiple Access Points (APs) to meet the fast-increasing demand for wireless access. In order to avoid network congestion which leads to issues such as suboptimal Quality of Service (QoS) and degraded user Quality of Experience (QoE), intelligent network traffic control is needed. Software Defined Networking (SDN) is an emerging architecture and intensively discussed as one of the most promising technologies to simplify network management and service

Abstract:

Common solutions to mitigating harmonics and improving power quality of power systems would include installing dedicated passive or active harmonic filters at the point of common coupling (PCC). However, as the complexity of energy systems increases with integration of renewables and storage systems on the one side, and the number of electronic loads increases rapidly on the other, the centralized compensation of harmonics may not be cost effective. At the same time, many modern loads and energy sources have high–bandwidth front–end power converters that present an opportunity for alternative

Maintaining the confidentiality, integrity and availability of such systems, mandates a rigorous prior analysis of the security risks that confront these systems. In order to analyze, mitigate and recover from these risks a metrics based methodology is essential in prioritizing the response strategies to these risks and also this approach is required for resource allocation schedules to mitigate such risks. In addition to that the Enterprise Objectives must be focally integrated in the definition, impact calcu

Abstract:

La croissante demande d'énergie électrique a conduit à la conception de systèmes électriques de grande complexité où les combustibles fossiles constituent la principale source d'énergie. Néanmoins, les préoccupations environnementales poussent à un changement majeur dans les pratiques de production d'électricité, avec un passage marqué des énergies fossiles aux énergies renouvelables et des architectures centralisées à distribuées. Les problèmes de stabilité dus à la présence de ce qu'on appelle les Charges à Puissance Constante (CPLs) constituent l’un des principaux défis auxquels sont confro

Abstract:

The number of electrical vehicles in Sweden are increasing faster for every year and the demand of charging them at home is growing as well. This requires high delivery reliability and a stable low-voltage distribution grid. In this master thesis three different low-voltage networks are modelled and simulated together with load which corresponds home charging of electrical vehicles (EV) to analyse if the grid is able to handle these kinds of stresses. Information of the different grids were gathered from Falu Energi & Vatten and modelled in Matlab together with EV charging loads generated

Abstract:

Recent years have seen a growing tendency that a large number of generators are connected to the electricity distribution networks, including renewables such as solar photovoltaics, wind turbines and biomass-fired power plants. Meanwhile, on the demand side, there are also some new types of electric loads being connected at increasing rates, with the most important of them being the electric vehicles (EVs). Uncertainties both from generation and consumption of electricity mentioned above are thereby being introduced, making the management of the system more challenging. With the proportion of

Abstract:

While IoT safety and security incidents continue to increase in frequency, scope and severity, there remains a gap in how the issue will be addressed. While the debate continues within academia, industry standards bodies, government and industry media, new entrants continue to rapidly enter the market with cheaper more powerful products with little incentive to address information security issues. In a free market economy, the supply and the demand would determine the product and services and the associated prices without intervention.

Those improvements and changes add up over time and increase thecomplexity of the system, which in turn prevents the company from further adaption.In order to change and improve existing business processes and their implementation withinsoftware, several stakeholders have to go through a long process.

Abstract:

This research aims to develop solutions to relieve system stress conditions in electric grids. The approach adopted in this research is based on a new concept in the Smart Grid, namely, demand response optimization. A number of demand response programs with energy storage systems are designed to enable a community to achieve optimal demand side energy management. The proposed models aim to improve the utilization of the demand side energy through load management programs including peak shaving, load shifting, and valley lling. First, a model is proposed to nd the optimal capacity of the batter
