A study of economic feasibility of Smart Community. - calculation of profit of Community Operator considering introduction of battery and co-generation systems
The idea of smart community which is expected to achieve effective utilization of energy at customer side, and contribute to stable operation of power system, for example peak shaving, et. is introduced recently. Since the smart community would optimize the local operation of the community that might affect the stable operation of distribution power system and whole power system, the development of cooperative operation method between community and power system is important. In order to develop the operation method of the community considering cooperation with power system, development of smart community model that is economically feasible is necessary. This report develops the economical evaluation model of smart community for arbitrary condition such as electricity price, purchasing price of generated power of PV, wheeling charge, et. and evaluate the economic efficiency of smart community. According to the evaluation results, a community operator can get benefit by operating community under the condition such as the lower penetration rate of PV, and higher rate of residential area that includes low voltage customers, in which the community operator can sell much electricity with expensive price to low voltage customers. By introducing co-generation system and utilizing exhaust heat for industrial area, the economic efficiency would increase and the community operator can get benefit from dealing with electricity transaction and selling exhaust heat to industrial customer. This paper also considers the Business Continuity Plan (BCP) and evaluates the maximum storage capacity under the condition that the community operator can get benefit, where the battery would be used for back-up power supply when the disaster occurred.
Smart community management portable device design based on embedded wearable device technology
ABSTRACT A broad definition Embedded Wearable Device Technology (EWDT) communication unites people around a common cause, interest, or smart community. The most basic kind is based on actual intimacy people in area, or older neighbors are essential to a wearable device relevant to the community's location. The natural part of the network with others around you and the Embedded Wearable Device Technology (EWDT) machine suing in the traditional economic system is continuously evolving. The risk is trapped in the state space model. The function of the expansion focus is to avoid the error money-related arrangement, primitive liquidity traps. Many business analysts avoid focusing on positive inflammation, even when the risk is low. The proof that the existence of an inflation trap has a slightly but beneficial effect on the presence of an inflation buffer. The assessment of the unfortunate work of the Bank sector is the descending, inclining capacity of the expansion target. Finally, these analytical features of the expansion target were verified by numerical methods. The embedded system changes because of the monetary trap. The private sector should Liquidity consider for real expansion goals.
Knocking in an Internal-Combustion Engine
The question remains open of the relation between the phenomena of knocking in the engine and the explosion wave. The solution of this problem is the object of this paper. The tests were conducted on an aircraft engine with a pyrex glass window in the cylinder head. Photographs were then taken of various combinations of fuels and conditions.
