Active utilization of energy demand in smart grids

A smart grid is a digitally enabled electrical grid that gathers, distributes, and acts on information about the behavior of all participants (suppliers and consumers) in order to improve the efficiency, importance, reliability, economics, and sustainability of electricity services. Moreover, as smart grids continue to support traditional power loads they also seamlessly interconnect fuel cells, renewables, micro-turbines, and other distributed generation technologies at local and regional levels. Integration of small-scale, localized, or on-site power generation allows residential, commercial, and industrial customers to self-generate and sell excess power to the grid with minimal technical or regulatory barriers. However, Smart grids require an important change in the infrastructure which represents a high cost that is difficult to cover in the short term. As phovoltaics has been regarded as a key technology for global warming mitigation in Japan, research is being done considering that the increase of PV’s into the grid could cause problems that threatens the stability and quality of the electric power system. To resolve this issues, this laboratory researches on energy management on residential area and the possibility of battery storage installation to deal with the energy surplus generated during the day which is later demanded on the evening. Some of the research topics are: “Evaluation of the effect of batteries in district level smart grid” “Household electricity simulation: demand, the electricity generation and demand-supply control methods”.

Other topics

Evaluation of Heat Supply System Performance

The thermal energy to supply cooling, heating, and hot water supply hold a large ratio of the total urban energy flow. Low-carbon technologies are being considered to achieve thermal energy conservation, such as district heating and cooling energy to supply heat applied in dense urban areas which have a large energy demand.  High efficiency heating systems are also being evaluated for each building (cogeneration, heat pumps etc. ), and several other systems have been proposed.

Some of the topics of this group are: “Energy conservation in district heating and cooling,” “The possibility of developing a business that services heat supply”, “Estimation of energy consumption efficiency by the duration of thermal source equipment”, among others.  We will propose a thermal system in the future based on the several assessments and accurate modeling of various systems that are being carried out.

Other topics

Modelling and Analysis of Building Energy Demand

This group researches on the actual energy consumption of buildings. In addition to the energy consumption analysis, energy conservation policies and measures for CO2 mitigation policies are evaluated. A simulation model has been developed in order to predict future energy consumption in the residential and commercial energy demand sectors. The building energy consumption depend on different specifications such as  lifestyle of resident behaviors, weather conditions, equipment specifications, etc.  The model developed by this group takes into account the structure of the energy consumption which enables to understand the impact caused by each one of the specifications above mentioned individually. By using this model, it is possible to measure the amount of carbon emission reduction while applying different methods for the mitigation of global warming.

Other topics

Urban Energy Metabolism

The debate for the optimization of the urban energy system is not only a discussion of the environmental impact caused by the energy consumption coming from every building, industry facility, etc., but it is also important to include the understanding of urban areas energy consumption and metabolism as a whole which can be generally evaluated in a input-output energy flowchart. As the sustainable technologies are being developed and are desirable towards a more sustainable urban energy system, this research group evaluates the urban energy’s flow considering the insertion of new technologies into the system.
