The definitions for active, reactive, and apparent powers that are currently used are based on the knowledge developed and agreed upon during the 1940s. Such definitions served the industry well, as long as the current and voltage waveforms remained nearly sinusoidal. Important changes have occurred in the last 50 years. New definitions in the Trial-Use Standard were developed to give guidance with respect to the quantities that should be measured or monitored for revenue purposes, engineering economic decisions, and determination of major harmonic polluters. The panel will discuss these issues.

Successful operation of a power system depends largely on the engineer's ability to provide safe, reliable and economic service to the customer. Advanced simulation technologies provide useful means to the engineer for the design and analysis of the power system, and assisting them in making reasonable decisions. Due to powerful software and advanced real-time simulators, it became possible to simulate the dynamic behavior of very large power systems including HVDC and FACTS, and to verify the performance of these complex systems with the original control and protection equipment in a fast and accurate manner. The simulation covers all stages of development and operation of a power system, such as planning, design, test and also during operation. In this paper, advanced software and real-time power system simulation technologies are presented. With practical examples benefits of the simulation for large power systems are also demonstrated.

The design of wholesale electricity markets through deregulation has focused almost exclusively on the development of competitive supply (generation). The demand side of the market has been virtually ignored. Mostly, this is due to the assumption that electricity demand is almost completely inelastic. As a result, deregulated wholesale markets universally fail to pass price signals down to the end-users. This paper challenges the assumption of inelastic demand by exploring the potential benefits of implementing a simple load control scheme. This load control scheme allows consumers to shift demand from high priced hours to low priced hours during the day. The benefits to the individual consumer are explored through an example applied to residential air conditioning using price and demand data from California. This example shows that "smart" use of air conditioning can lead to great savings for residential consumers, without sacrificing comfort. The potential for multiple consumers implementing load control to reduce wholesale prices is also examined.

This paper discusses the regulatory, commercial and technical issues relevant for the development of the environment in which distribution network and distributed generation businesses will operate in the European electricity market. The primary function of the distribution network is now changing from an electricity delivery role to a facilitator of competition in generation and supply. This is believed to be critical for distributed generation to access the energy market and compete with central generation. This will inevitably lead to unbundling of distribution network services and this paper discusses a how distributed generation may interact with distribution network operation.

This paper presents an adaptive protection scheme for transmission lines based on synchronized phasor measurements. The work includes: fault detection, fault classification, and fault direction discrimination. Using two-terminal synchronized measurements incorporated with distributed line model and Clarke transformation theory, fault detection index is derived. We can classify the faults by the proposed modal fault detection index and the circuit breaker can achieve single-pole tripping. The fault detection index is composed of two complex phasors. The fault events can be found according to the angle difference between these two phasors as in internal and external fault situation. The proposed method also combines on-line parameter estimation to assure protection scheme performance and to achieve adaptive protection. After a lot of EMTP simulations and verifications show that the method provides a fast and accurate protection scheme for transmission lines. The tripping decision time of the protective relay is within 1/2 cycle.

Multifunction microprocessor-based protection relays and intelligent electronic devices (IEDs) have created new opportunities for the measurement of power system signals and their diagnosis. The quantity and complexities of the information has been enhanced to the extent that it is well beyond what is required for the immediate operational issues. A significant amount of data is now continually available and during a serious operational incident or fault, it may become excessive and impossible for a substation operator to handle. A technique used to extract concise information from the data received from microprocessor-based relays will be described in this paper. The data analysis technique is based on rough set theory, which has already been used in many areas of artificial intelligence including machine learning and knowledge-based system. A 33/11kV distribution network was modeled under different types of fault scenarios using EMTDC. The resulting event database was uploaded into the Rough Set Data Analysis Module (RSDAM), which eliminates superfluous data whilst keeping all the essential information.

It is not uncommon to encounter electric utilities that have not recorded the phasing of laterals in their distribution circuits. This lack of information hampers many studies such as multi-phase power flows and restoration analysis. To obtain the phasing information with manpower-intensive techniques often requires a long term and expensive effort. This paper addresses a low cost, algorithmic approach for estimating the phasing of laterals. The algorithmic approach uses circuit measurements and load information that is available at most utilities. The algorithm employs the tabu search method. Examples are presented.

Power systems can become vulnerable in the face of possible power system abnormalities. To maintain system reliability becomes a serious concern for the future. The SPID project was launched by EPRI/DoD to understand the origin and nature of catastrophic failures and to develop defense strategies and technologies that will significantly reduce the vulnerability of the power system infrastructure. The approach is characterized by the extensive use of network and real time information from diverse sources, coupled with the development of an evolving dynamic decision event tree. This paper examines the communication issues for the SPID system including information transmission network design and data exchange architecture design. A communication infrastructure design for the SPID system is also proposed. Rather than specifying the detailed network design, the paper provides an overview of the architecture issues.
