Networks with differing parameters can be linked, and voltage stability and power quality are influenced positively. The scope of new applications using power converter technology is presented, and specific applications are explained in this paper. This paper shows what scope is offered by innovative power supply systems for enhancing supply conditions and cutting costs. DC long-distance transmission and back-to-back links are nothing new in the high-voltage sector. The advances made in power electronics mean that such systems are also of interest for medium voltage. With SIPLINK (Siemens multifunctional power link), Siemens has developed a system for medium voltage, which cuts investment costs, system costs and lifecycle costs - depending on the particular application and configuration of the existing network. SIPLINK controls load flow in power transmission and optimizes voltage stability by provision of reactive power.","PeriodicalId":427228,"journal":{"name":"2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies.

Principal-agent model is employed in risk-evasion incentive contract design. The utility's optimal contracts are developed with considering risk-averse and risk-taker customers respectively, the correlation of market price and retail price is also considered in contract design.

This paper discusses harmonic voltage control using a shunt active harmonic filter based on a voltage detection method. The control method is discussed first. Compensating currents at individual harmonic orders are generated via the transformation of three-phase voltages into d-axis and q-axis voltages on the synchronous reference frame at harmonic frequencies of concern. A complex control factor, which can be adjusted in both amplitude and phase angle is introduced to achieve optimal operation of the filter under different natures of supply network. Simulation results by computer software are obtained and presented finally to demonstrate the effectiveness of the active harmonic filter.","PeriodicalId":427228,"journal":{"name":"2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies.

The major function of OEEN is to maintain energy balance with respect to bilateral transactions so as not to cause line overloading. In order to achieve the function, many storage devices are distributed in the network, and which are controlled by a management system named as power router. The power router acquires information about bilateral transactions and power flows through a communication system to make a charge-discharge schedule of storage devices. The mobile agent discussed in the paper supports the information acquisition and the charge-discharge scheduling of storage devices, and which is called power router support agent (PRSA). We also discussed about another mobile agent to manage many storage devices in OEEN, and which is called storage device management agent (SDMA). The mobile agent is a kind of computer program which can deal with some works ordered by its user and also move within computer networks such as Internet.","PeriodicalId":427228,"journal":{"name":"2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies.

Blackouts rarely happen and are usually caused by a sequence of low probability disturbances. The sequence of low-probability disturbances is generally not planned by the system designers and is not expected by system operators, making a power system more susceptible to a blackout. There are a number of other contributing factors that allow a blackout to spread. There is no single solution to prevent blackouts, but there are general measures than can and should be taken to minimize impact of wide area disturbances.","PeriodicalId":427228,"journal":{"name":"2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies.
