Impact of Dynamic Tariffs for Smart EV Charging on LV Distribution Network Operation

With a growing share of electric vehicles (EVs) in our distribution grids, the need for smart charging becomes indispensable to minimise grid reinforcement. To circumvent the associated capacity limitations, this paper evaluates the effectiveness of different levels of network constraints and different dynamic tariffs, including a dynamic...

A Co-simulation Framework for the Provision of Support Services by Smart Residential Users in LV Distribution Systems

In this paper, a co-simulation framework is presented to assess the impact on the distribution network of provision of support services (i.e. voltage support) by smart residential users. Such users are capable of providing flexibility by increasing/decreasing generation/consumption controlling the operation of an available set of flexible...

The impact of weather and of batteries on the investment risk for backup gas power plants in a largely renewable energy system

With an increasing wind and photovoltaic share, the German generation mix becomes more weather-dependent. Backup technologies can help to bridge scarcity moments. These rare moments with high prices are the main events for their cost recovery. However, the uncertain revenue flow combined with long payback periods leads to high investment...

Markets for Direct Current Distribution Systems: Towards Energy-based vs Flex-based Designs

Direct Current Distribution System (DCDS), a promising alternative to existing AC systems, connect customers to DC energy sources without AC/DC conversion. The unique features of DC, including the power-voltage coupling effect, impose different requirements to DCDS operation compared to AC. Addressing a liberalized energy market, this paper...

Dynamic Planning for Flexible Port Infrastructure after Panama Canal Expansion: A Real Case Study

This paper presents a study carried out to first assess the impact of the Panama Canal expansion (PCE) on selected Caribbean ports, and thereafter, to examine how the ports can adapt in order to seize new opportunities created by the expansion. An applied case of long-term dynamic planning and flexibility in engineering design is presented for a...

Towards sustainable infrastructure with planned adaptation

In the present turbulent environment, adaptability and robustness belong under the overarching definition of sustainability. Sustainable infrastructures should not only achieve economic, environmental, and social objectives, but should be robust and adaptable under uncertainty. This paper examines the current guidelines for port development and...

Electricity Market for Direct Current Distribution Systems: Exploring the Design Space

Direct current distribution systems (DCDS), which connect local prosumers directly to community grids without AC/DC conversions, are a promising alternative to AC systems. While regulations call for market-based operation, existing markets for AC systems do not meet DC requirements and cannot be applied to a DCDS. This paper develops a design...

Evolution of housing

‘Perfection means something is complete and stands still and what stands still doesn’t change or evolve and is automatically dead. Everything in the universe changes, evolution implies that the creation is not complete hence the possibility of evolving’ (Osho, 1985). Our society and economy are constantly changing. Hence the demands and wishes...

Role of Flexibility in Sustainable Port Development

Sustainability has become a high profile objective in all aspects of our lives, including the development of our infrastructures. Flexibility can enhance sustainability endeavors, yet its contribution is not clear to most. In this paper we investigate the role of flexibility in sustainable port development in order to promote its incorporation...

Flexibility in port infrastructure

The present volatile environment continues to place new functional requirements on port infrastructure. As a result, the useful life of port infrastructure has reduced in recent years. Flexibility in infrastructure makes it possible to adapt them for new or changed use. The use of flexible and sustainable solutions infrastructures needs to be...

Conflicting flexibility

New buildings are designed for first users. For a sustainable approach there are many advantages in designing in flexibility and adjustability in order to enable and facilitate the other sequential users. For the first investor this flexibility is translated into improved exit values due to increased potential. The second investor is acquiring a...

Flexibility in Port Planning and Design

Recently, flexibility has received much attention from port researchers, designers, and managers. That is because the stability of the competitive environment of the past has been replaced by increasing uncertainty. The current economic crisis and the recent trends in ports and shipping sectors are causing port planners to rethink their approach...
