Attitudes Toward Professional Foreign Players in Finnish Amateur Basketball
1984
The use of foreign professional players may influence the host country's sport culture. To determine the attitudes toward foreign professionals in various Finnish amateur basketball leagues, all clubs (n = 55) playing basketball in the three highest Finnish leagues were interviewed by mailed questionnaire. The results indicated that recruitment of foreign pros was held to effect negatively the team spirit and the play tactics, the economics of the club, the development of other sport branches in the club and the success of the national team. Positive effects were expected on the number of spectators, public relations of the club and the success of its team. For lower leagues foreign profes…
Economic performance assessment of building integrated photovoltaic system with battery energy storage under grid constraints
2020
Abstract In this work, a typical South Norwegian house with BIPV system is considered for potential application of on-site battery energy storage. Economic and technical operation performance analysis has revealed that such a system can perform techno-economically much better compared to its counterpart. Techno-economic performance of BIPV system with appropriate energy storage has been evaluated for grid power supply limits with appropriate energy tariff for minimizing the annualized energy cost. It has been assumed that the capital costs associated with PV has been included in the building mortgage and expected that in the near future, the grid power supply limits would be introduced and …
Economic impact of medium-scale battery storage systems in presence of flexible electricity tariffs for end-user applications
2012
This article addresses the question if it is cost-effective to use medium-scale battery storage systems for time-of-use (TMO) energy cost applications at a consumer level, assuming flexible electricity tariffs in the Italian electricity market. TMO application allows customers to reduce their electricity bill charging the storage when off-peak time periods are applied and discharge it during on-peak periods, when electricity energy prices are high. The analysis is carried out taking into account three different electrochemical storage technologies. The economical comparison shows that, at the current costs of storage technologies and at the electricity tariffs currently offered in Italy, th…
Impacts of electricity pricing on techno-economic performance of photovoltaic-battery centered microgrid
2021
The energy management technique in a microgrid, plays very crucial role for making it more economic viable during the electricity energy pricing dynamics. It is vital to investigate the impact of e...
The scenario of electric vehicles in Norway
2017
Abstract Electrical vehicle (EV) technology is widely recognized as one of most important transport measurements, as it does not emit greenhouse gases and noise while reducing the crude oil dependency. EV prices, driving range, and battery types are the main decisive challenges in EV industry. Currently, Norway is the leading country in EV by introducing economical and efficient incentives that have a direct impact on increasing the EV buying rate. The economic incentives such as exemption from vehicle taxes have reduced the EV prices. Moreover, flexible charging infrastructure has increased the battery range by establishing fast and slow charging places around the country. The EV usage is …
Stationary battery systems in the main world markets: Part 2: Main trends and prospects
2017
Stationary battery systems are gaining a lot of interest in recent years, mainly because of their ability to balance generation and demand of electricity over time. The intermittent nature of renewable generation connected to the power grid is causing major stability and reliability issues in the power system, that can be solved also using stationary storage systems, able to provide the ancillary services necessary to the proper operation of the power network. Despite the considerable advantages offered by these technologies, the electrochemical storage industry is still in the nascent state and it is important to identify the main trends and prospects in relation to future technical develo…
Techno-economic evaluation of PV based institutional smart micro-grid under energy pricing dynamics
2020
Abstract The solar photovoltaic (PV) system with battery energy storage have a lot of potential to provide reliable and cost-effective electricity and to contribute in micro-grid operation. However, the operational performance of such type of micro-grid system depends on many factors (e.g. techno-economic sizing, energy management among the sources, market energy prices dynamics, energy dispatch strategies, etc.). In this paper, a typical Indian institutional energy system has considered for techno-economic performance evaluation for operating as a smart micro-grid under market energy pricing dynamics. The institutional energy system has integrated PV, battery storage and DG for operating a…
Optimization of urban delivery systems based on electric assisted cargo bikes with modular battery size, taking into account the service requirements…
2021
The implementation of new forms of urban mobility is a fundamental challenge for improving the performance of city logistic systems in terms of efficiency and sustainability. For such purposes, the exploitation of electric vehicles is currently being investigated as an alternative to traditional internal combustion engines. In particular, the employment of lightweight electric cargo bikes is seen as an attractive possibility for designing improved city distribution systems. Such vehicles, however, present substantial limitations related to their endurance, speed, power, and recharging times; therefore, their configuration must be optimized considering the actual operational context and the …
An integrated energy simulation and life cycle assessment to measure the operational and embodied energy of a Mediterranean net zero energy building
2022
Abstract Net Zero Energy Buildings can play a key role in reducing the energy use, greenhouse gas emissions and the use of natural resources associated to the built environment. It is widely recognized that in low energy building a shift in relevance may occur from the operational to the embodied impacts. However, building performance assessment focus mostly on the operational phase and on primary energy consumption. This study aims to assess the energy and environmental impacts of a residential net zero energy building expanding the analysis to the full life cycle and to a wide range of environmental impact categories. The methodological approach integrates a non-steady state building ener…
Battery Capacity Estimation for Building Integrated Photovoltaic System: Design Study for Different Geographical Location(s)
2017
Abstract Building Integrated Photovoltaic system (BIPV) with energy storage (ES) can help in reducing the peak demand, improving the power quality and control dispatching of the power. Adding a proper size of battery ES to the grid-connected PV system could reduce the overall investment cost as well as reducing the grid-dependency. A typical battery energy storage capacity is going to be determined by considering the real-time operational (PV production as well as load consumption) data. In this study, real-time operational data of a residential load (C6 house) with BIPV system located Southern Norway as well as institutional load (Teri university) with BIPV located in New Delhi, India are …
