Abstract: Today the elaboration degree of wind meteorological information far from enough, which leads to the low wind farm wind power prediction accuracy, causing grid scheduling problems , so as to result in instability in power systems easily. This paper selects zinc bromide battery energy storage system for the measurement of improving the forecast accuracy of the wind farms, adopts fuzzy control and sets up fuzzy control rule base for the energy storage system considering the error probability characteristics and the charge state SOC of the energy storage to control the storage charge and discharge power, and does simulation analysis of a wind farm in XinJiang which introduced into the energy storage. At the same time, compared with the traditional control strategy the results indicate that fuzzy control strategy of energy storage system can more effectively improve the wind power short-term forecast accuracy significantly,80% of the predicted value meet the requirements of the state grid has less than ± 25%.

Abstract: In this paper, the problem of increasing the energy capacity of compressed air used as a mobile carrier of energy is considered. An idea of preliminary Joule-Thomson self-heating of the compressed air with the following heat redistribution to obtain the maximal work at maximal power is considered. A simple circle combination of a heat exchanger and a throttle device-Linde-Hampson anti-machine - is analyzed. Calculations performed in the framework of modified van der Waals gas model show essential increasing of accumulated specific energy of compressed air fuel to the range 0.5-1.0 MJ/kg which is comparable with electrochemical fuel energy. A concept of compressed air fuel production is discussed.

Abstract: New vehicle electric systems are promoted by the needs of fuel economy and ecology as well as by new functions for the improvement of safety and comfort, reliability, and the availability of the vehicle. Electrically controlled and powered systems for braking, steering and stabilization need a reliable supply of electrical energy. The planned generation of electrical energy (only when it is economically beneficial meaningful), an adequate storage, and thrifty energy housekeeping with an intelligent integration of the battery as the storage medium into the overall concept of the vehicle Energy Management, and early detection of possible restrictions of reliability by Battery Monitoring allows for actions by the Energy Management well in advance, while the driver need not be involved at all. To meet today’s requirements for Battery Monitoring and Energy Management, solutions have been developed for series vehicles launched in years 2001–2003, operating at the 14 V level. In this paper, Battery Monitoring and Management has been done by considering the change of lead-acid battery properties over life, including grid corrosion, water loss, changes of active material properties, loss of active material availability, etc. Also, Battery Monitoring and Power Management to provide cranking capability several days ahead is also analyzed.

Abstract: Measuring the environmental efficiency of countries is important in the climate change process. The aim of this paper is to measure the energy efficiency of OECD countries with undesirable output. For this purpose, the Bad Output index (non-radial and non-oriented, CRS) developed by Tone (2001) is used in order to obtain the efficiency scores for the period 1995-2009. In this paper, I focus on the production process where labour, capital stock (mostly omitted in such papers), and energy consumption are inputs, GDP is a desirable output and CO₂ emission is an undesirable output. To see the energy inefficiencies separately, if there are any, energy input is considered as three separate variables in the model. For this purpose, oil and natural gas consumption are incorporated as one input. Hydropower and nuclear are incorporated as another input. Coal is the third input. An important contribution of this paper is to use various proxy variables for the capital stock. Determining the reasons of these inefficiencies is important for these countries. But modelling the factors behind these inefficiencies is the subject of another paper.

Abstract: Building material and components play a crucial role in solar buildings construction and planning. The literature review of the research emphasize that solar architecture and building integration is in need of some productive design strategies which focuses on reuse of recycled building materials. This paper aims at suggesting a mechanism for optimal use of recycled materials in construction industry which serve energy efficiency as one of the top priorities. The research questions are: 1- what are the priorities of using recycled material as related to energy efficiency issues? 2- Which recycled materials can be used in construction to meet energy efficiency in solar buildings? Recycled cellular glass is selected as research sample to develop inference mechanism. A combination of qualitative and quantitative methods as well as problem solving approach are used in this study to answer the research questions related to construction industry particularly energy protection. The findings indicate increase in energy price and increase in the difference between cost of melting raw materials and melting recycled glass; and enactment of regulations for reducing extraction of raw materials and using recycled ones instead in construction projects can significantly affect the cost-effectiveness of using recycled materials in producing cellular glass; especially in contemporary architecture and future ZEB sustecture. In the other word recycled building materials can be adopted in solar architecture to energy efficiency.
