The energy sector is experiencing a revolution that is fuelled by a multitude of factors. Among them are the aging grid system, the need for cleaner energy and the increasing demands on energy sector. The demand-response program is an advanced feature in smart grid that strives to match suppliers to their demands using price-based and incentive pro...

Demand Side Management, DSM, is a program supported by the smart-grid which aims at matching the energy consumption and production. Several techniques for demand-side management have been proposed, including load-shedding, time of use pricing, real-time pricing, and critical peak pricing. In this work, we propose a distributed load-shedding algorit...

To improve the living standard of urban communities and to render the healthcare services sustainable and efficient, e-health system is experiencing a paradigm shift. Patients with cognitive discrepancies can be monitored and observed through the analyses of power consumption of home appliances. This paper surveys recent trends in home-based e-heal...

The increasing interest in integrating renewable energies source has raised concerns about control operations. The presence of new energy sources, distributed storage, power electronic devices and communication links make a power system’s control and monitoring more complex and adaptive than ever before. Recently, the use of agent-based distributed...

Smart-grid is a complex system that incorporates distributed control, communication, optimization, and management functions in addition to the legacy functions such as generation, storage, and control. The design and test of new smart-grid algorithms require an efficient simulator. Agent-based simulation platforms are the most popular tools that wo...

The research projects in ICT need to embrace new dimensions. Traditionally, research group work in an isolated manner and is conducted in a purely academic way. This type of research is outdated and needs to be more innovative, engaging and address societal challenges from the local perspective. Quadruple-helix model is a concept that ties together...

Innovation is increasingly becoming a key driver of economic growth globally. To unlock people’s innovation potential and benefit from the innovation process, one of the ways used to entice people in innovation is the use of competitions and awards. However, little research has been done to determine the influence of competitions and awards in inno...

In the knowledge-based society, the legacy education system does not provide the needed skills for creative engineers especially enhancing student innovation and entrepreneurship capacity. Triple-helix model is a concept that aims to bond universities, industry and government in a bid to create innovations. In Europe, integrating research, educatio...

This article describes a framework for load shedding techniques using dynamic pricing and multiagent system. The islanded microgrid uses solar panels and battery energy management system as a source of energy to serve remote communities who have no access to the grid with a randomized type of power in terms of individual load. The generated framewo...

This paper presents a framework of load shedding experiment for a DC Microgrid using Multi-Agent System (MAS). The microgrid uses solar panels as source of energy to serve a community without access to electricity. The generated framework includes modelling of solar panels, battery storage and loads for effective control and better operation. The l...

Smart micro-grids are low voltage autonomous power systems that integrate information and communication technologies with electrical energy systems in a complex system that can generate distribute and store power more efficiently. In order to realize this, it is important to find the optimal configuration of components that will result in the most...

This paper proposes a Multi-Agent System (MAS) modeling and control architecture for a solar driven DC microgrid. The microgrid consists of solar system as a source of power, energy storage system, critical and non-critical houses (loads) with their own solar and storage as well. The proposed MAS aims at increasing power production in the microgrid...

The need for creative engineers using natural sciences as their approach has not drastically changed in the past 100 years. However, technology advances have created new challenges and brought new opportunities, which calls innovation in engineering education. Todays, and even more so tomorrow´s engineers need to be equipped with both technical and...

Due to changes in the market positions of old companies caused by innovation in technologies, services, business concepts and global challenges faced by nations in terms of climate and safety, academic systems in Europe have started to look into new pedagogical models and strategic partnerships. The new systems that connect research, education and...

The smart grid is a new paradigm that aims to modernize the legacy power grid. It is based on the integration of ICT technologies, embedded system, sensors, renewable energy and advanced algorithms for management and optimization. The smart grid is a system of systems in which communication technology plays a vital role. Safe operations of the smar...

Development of software systems based on agile software development methods have become popular solution on problems associated with technology changes and requirements need. In Tanzania, this method has not yet practised in the field of computer science due to lack of motivations and tools to work with agile software development. In this work diff...
