This paper discusses the evaluation of interconnection capacity of small cogeneration(SCOGN) systems to the power distribution systems from the viewpoint of voltage regulation. Power utilities are required to keep the customers' voltage profile over a feeder close to the rated value under all load conditions. However, it is expected that the interconnection of SCOGNs to the power distribution systems impacts on the existing voltage regulation method and customers' voltage variations. Therefore, SCOGNs should be integrated to the automated power distribution systems to prevent interconnection problems and supply high quality electricity to the customers. For these reasons, we should proceed with the evaluation of interconnection capacity of SCOGNs to the power distribution systems. However, it is generally impossible to perform actual testing on the power distribution systems, and standardized methodologies and guidelines are not developed to evaluate it. The criterion indexes for voltage regulation and variations are presented in order to evaluate the interconnection capacity of SCOGNs to the power distribution systems. In addition, the evaluation methodology of interconnection capacity of SCOGNs for power distribution systems is presented. It is expected that the resulted of this paper are useful for power system planners to determine the interconnection capacity of SCOGNs and dispersed storage and generation (DSG) systems to the power distribution systems.

For the efficient interconnection between SMDS and LAN, an interconnection protocol architecture in the router is proposed in this paper. A control method of xongestion which is produced by this interconnection of SMDS and LAN is also proposed. Especially, the SIP level 3 of SMDS is devided into CS-SIP3 sublayer and CLNAP sublayer in order to circumvent the problems which are producted by the protocol difference of two networks and to consider the interconnection with B-ISDN in the future. In this way, the interconnection of SMDS and LAN is transparentlly achieved through CLNAP layer, and the interconnection protocol architecture becomes simple. To test the performance of the router, amodel of interconnection protocol which is proposed by this paper is simulated using sliding window flow control. The simulation results show that the throughput of router is increased. The packet delay and the rate of packet discard are also decreased.

In this paper, a method for computing the capacitance parameter for a multi-interconnection line in a multilayered dielectric region is presented. The number of interconnection lines and the number of dielectric layers are arbitrary, and the interconnection lines are finite cross section or infinite cross section. The surface of lines and dielectric interface are divided into subsection. The surface charge density of each subsection is a constant step-pulse function for each subsection. After the solution of surface charge density is effected by the method of moments, capacitance parameter is calculated.

A design method of decentralized state observer for large scale interconnected systems is proposed by the use of interconnection rejection approach and interconnection modelling technique. The proposed design method is developed based on the interconnection partitioning. Therefore partitioning conditions are suggested. And the conditions for observer pole assignment and observer parameter determination procedures are described for possible interconnection patterns. The decentralized state observer gives good estimates without any information on the interconnection variables and estimations. In addition, a numerical example is given to explain the design procedures and to show the estimation performance of the decentralized observer.

In this paper, an intelligent home network middleware interconnection adapter between devices was designed. Home network middleware interconnection adaptor is present in UPnP, LonWorks, LnCP, HAVi, etc. Various types of middleware and for use of a number of middleware is required to modify an existing system. But this study designed by middleware interconnection adaptor a number of existing middleware systems without modification was designed to allow interlocking. The Performance evaluation of designed interconnection middleware adaptor produced by various companies was used devices, experimental device was implemented. And mobile application was developed by using developed interconnection middleware adaptor. Also the performance was evaluated in a mobile application.

This paper propose how to calculate the capacitance for VLSI interconnection lines in multi-dielectric layer. The proposed method is a expansive form of 3-dimensional direct intergral method developed in single-dielectric layer. We took into consideration the effect of multi-dielectric layer by using additional boundary condition instead of modified Green's function. It is used the potential equations in line surface and the electric field equations in dielectric interface as the boundary condition. RC delay time for interconnection line of multi-dielectric layer is obtained from the calculated capacitance value. At this time, we are used Al and WSiS12T as interconnection materials.

This paper discusses current internet interconnection issues according to radical changes of internet traffic pattern. In this context, the recovery of network investment cost for network provider becomes hot issue. For recovery issues of investment cost, there are many disputes among stake holders. Therefore, it is necessary to investigate this issues in the context of internet interconnection. Also, it is important to develop the current regulation about internet interconnection under traffic changing environments. This paper selects four issues to deal with and analyzes the present situations and problems about these issues, and provides alternatives for internet interconnection corresponding to these four issues.

When DG interconnection into network is examined, details of the review are overvoltage, protective device malfunction, etc. In the case of protective device malfunction, replacing protective device into bi-directional protective device and installation NGR are the solution. Overvoltage at interconnection point occurs because the load is relatively less than DG output. When overvoltage at interconnection point occurs, DG interconnection is not permitted because this overvoltage affect other customers. Interconnection by installation new distribution line is one solution but it costs much money. Without installation new investment, change of NOP(Normal Open Point) position is a possible solution about DG interconnection into network.

The study on Wholesale pricing of MVNO using two way interconnection charge system is rare. This paper considers MVNO possessing its own facilities and subscribers. While previous studies focus on wholesale provision by MNO, this paper employs another approach from existing MVNO model. This paper introduces two way interconnection charge system by recognizing that mobile network interconnection is important to complete the call from MNO to MVNO as well as the call from MVNO to MNO. Also it is interesting to analyze wholesale pricing when there is brand loyalty between MNO and MVNO. This paper analyzes retail pricing and wholesale pricing under duopoly competition and drives social optimal solutions using linear city model.
