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.
ESTIMATION OF PV SYSTEMS POWER PRODUCTION EFFICIENCY IN THE DENSE URBAN DEVELOPMENT CONDITIONS
The paper describes the preconditions for planning and building an intelligent community of Energy Smart Community. The state of RES sector development, namely, PV stations in the energy structure of the United Energy System of Ukraine, has been characterized. The features of building an Energy Smart Community architecture include an analysis of the possibilities of joining their own generating capacities as an energy component in this system. The energy and economic criteria for such type of intelligent community are described. The article analyzes the foreign experience in building and implementing Energy Smart Community in power systems on the basis as pilot projects NYSEG and SCA for its further scientific research and testing. Using the software module in the Matlab Simulink environment, we have constructed and described the work on the example of an arbitrary PV module, with its principal dependencies being distinguished from the generalized solar insolation index. The obtained data point to all the prerequisites for the possibility of widespread participation of private PV systems of power supply as the main asset of the Energy Smart Community.
Representation of systems disturbed by wide band noise
In this paper, a method of handling and working with wide band noise is developed. We represent wide band noise as a distributed delay of white noise and use it to reduce a nonlinear system disturbed by wide band noise to a nonlinear system disturbed by white noise. An application of this reduction to a nonlinear filtering problem under a wide band noise disturbance is discussed.
