W artykule omówiono zagadnienia związane z wdrożeniem demonstracyjnego układu gromadzenia energii w stacji elektroenergetycznej. Przyjęto, że celem działania zasobnika w stacji SN/nn jest modyfikacja profilu obciążenia obiektu przez zmniejszenie współczynnika szczytu. Omówiono algorytm sterowania zasobnikiem, jak również dokonano oceny efektywności zastosowania takich rozwiązań w przyszłości.

The electric vehicle (EV) has become a popular topic because of the increasing scarcity of energy sources and growing environmental pollution. Unit commitment (UC) with plug-in hybrid electric vehicle (PHEV) for cost optimization is presented in this paper. The profile of charging load and vehicle-to-grid (V2G) power of PHEV is forecasted, and various scenarios with different PHEV control strategy are simulated. Quantuminspired binary particle swarm optimization algorithm with heuristic strategy has been employed to solve the UC problem. Results show that PHEVs will significantly affect the UC problem. PHEVs bring on new load demand to power system, which will increase the generation cost. However, the coordinated charging strategy and reasonable usage of V2G power can reduce the generating cost.

Availability and access to energy are considered as catalysts for economic growth. Harnessing clean energy for sustainable development is the keyword in today's scenario of energy utility. With the transport sector, contributing 32% of the total pollution levels, development and increased utilization of hybrid electric vehicles would be the best possible method to adopt for a cleaner and greener tomorrow. While lithium-ion technology is expected in production HEVs in the very near future, use in PHEVs are expected to be more gradual and dependent on solving the life, safety, and cost challenges. As a result, battery technologies for EVs are not fully matured due to range and charging-time issues, which are yet to be addressed. These two issues are normalized substantially in our study as the result of implementation of a battery swapping technique, thereby fast charging the batteries. This study focuses on battery systems as the electrical energy storage device and thus evaluates commercially available technologies for PHEV penetration in India through use of renewable energy sources such as wind and solar power in specific demographic areas as a typical example. The three-wheeler vehicle, popularly known as auto-rickshaws are one of the most important type of commercial transportation in majority of the Indian cities. An example of such a typical urban use auto rickshaw is considered for our study. This project has three main objectives: To convert the existing three wheeler into a PHEV and to determine the state of technology for PHEV batteries through an extensive literature review, develop a battery pack model and its charging cum swapping station at the above two places using renewable energy sources and finally to assess the environmental benefits of greenhouse gases emission, CO2 reduction and decrease in fuel consumption.

Obecnie obserwuje się wzrost zainteresowania pojazdami elektrycznymi i ich wykorzystaniem nie tylko do celów transportowych, lecz również jako zasobniki energii elektrycznej dla rozproszonych źródeł energii. Powoduje to wzmożone poszukiwania układów zasilania umożliwiających wysokosprawny i dwukierunkowy przepływ energii. Jednym z takich rozwiązań jest Indukcyjny System Bezstykowego Zasilania ISBZ z dwukierunkowym przepływem energii. Powyższy system charakteryzuje się przekazywaniem energii poprzez pole elektromagnetyczne, co powoduje że konstrukcja nie zawiera elementów stykowych pomiędzy stacją ładownia a pojazdem pracujących w zmiennych warunkach środowiskowych i narażonych na uszkodzenia. Artykuł prezentuje analizę i wyniki badań powyższego systemu.

Today has been a growing interest in electric vehicles and their use not only for transport purposes, but also as containers for electricity distributed energy sources. It cause increased exploration of supply system, allowing bidirectional and high efficient energy transfer. One such solution is a Inductive contactless power system ICPS with bidirectional energy flow. This system characterized by the energy transfer through electromagnetic field, and lack of contact elements hold the EV electric vehicle or another charging devices. ICPS can be used under varying environmental conditions even in explosive atmosphere. The article presents an analysis simulation results of the above system.
