General Terms

The successive energy crises, usually linked to the rising prices of oil, bring about new topics of the energy systems management in general terms. Over all, the electrical system is one of these cases. In addition, a greater concern for environmental issues has introduced, to a greater or lesser extent, the generation from renewable sources in the electrical system. In this context, the possibility of developing and using electricity storage systems would manage mismatches between generation and demand at electricity networks, making them more efficiently. In this research, we propose a number of possible strategies based on technical peak shaving and valley filling. The tool is used as energy storage systems in general terms, regardless of the accumulation technique used. The classification of strategies essentially serves two criteria: optimization service and increased profitability.

Efficiency And Effectiveness

The substations are important parts of modern electrical grids. The monitoring of background information in substations should be carefully managed to keep the smoothly operating of the electrical system. However, there are still some problems in present substations. As a result, some problems can not be handled efficiently and effectively. In order to improve the robustness of information monitoring of substations, this study first analyses the typical problems in the substations. Afterwards, several ways are proposed to handle these problems. As all the information in the substations are standardized, classified and automatically diagnosed, the occurred problems can be smoothly solved with high efficiency and effectiveness.

Waste Handling

This project investigates the treatment of wastewater from two car washes using a biofilter of peat and carbon-containing ash. An evaluation of the efficiency and waste handling of the filter material was done from an environmental perspective. The biofilters were used during 2 and 4 years respectively. The treatment included an oil separator and a peat/ash biofilter. The main function of the oil separator was to reduce the amount of oil in the wastewater. The peat/ash biofilter was used as a second step of the system to treat mainly heavy metals. A comparison with the guiding values for wastewater from car washes in the municipality of Kristianstad showed that this type of filter works well. Wastewater from car washes may contain many different unhealthy and environmentally dangerous substances such as surfactants and aromatic compounds. More tests are needed to investigate if the treatment method reduces such parameters from the wastewater as well. After usage the filter is considered solid waste and is to be classified and handled according to that. Classification of the filter as waste requires knowledge about the content of environmentally harmful substances in products used in the car washes. As the content of non-analyzed substances in the filters was unknown, combustion was regarded to be an environmentally good way of disposing the filter material as both energy and ashes are recycled.
