An example of how effective ASP-based, wholesale energy market online analytical tools work is illustrated in this paper. The ASP collects and processes the necessary data and hosts them on secure database servers. The data may include historical and real-time load data, weather data, power flow cases, transmission grid data, market bids data, etc. Seamless platform-independent software integrates the complex analytical engines with the database and application web portals. To assist the energy market participants, several analytical functions can be brought online, such as load forecasting, pricing forecasting, transmission rights auction simulation, transmission congestion analysis, etc. All these are hosted at a reliable remote site. Users can access these online tools via an Internet portal provided by the ASP.

Extensive growth in distributed generation (DG) presents challenges for the ability to maintain frequency on the electric power system. There is little impact on frequency stability for small DG penetration. Once DG reaches critical mass, however, the current methodology for generation-based frequency compensation, automated generation control (AGC), may be insufficient to maintain frequency within the bounds for service quality. Some DG units, such as microturbines, are capable of contributing to frequency control. Renewable energy based DG units, such as wind and solar, however, are not controllable and therefore cannot participate in frequency control. In the following cases: Stand alone mini-grids, or a high penetration of DG in interconnected grids, augmenting the capability of DG to provide frequency compensation may be necessary to ensure power quality. This paper investigates demand based frequency control to provide such compensation. Both the technical and economic aspects of implementing demand based compensation are evaluated.

The proliferation of different nonlinear and electronically switched loads has the potential to greatly elevate the harmonic distortion levels on the electrical distribution systems. The effect of different system and load parameters on the harmonic distortion is investigated. The attenuation and diversity effects represent the main factors that affect the system pollution. The effect of changing the inductive source impedance X/R ratio, system loading levels, load combination and nonlinear load position on the overall system distortion and the three-phase four-wire system neutral current and neutral to earth voltage (NEV) is studied. The analysis uses the time domain approach and utilizes the Electromagnetic Transient Program (EMTP) to model the different harmonic producing devices.

Compared with object-oriented programming, agent-oriented programming provides higher level abstraction and encapsulation. The software agents are autonomous entities with abilities to adapt the changing environments. An example of carrying out a circuit breaker maintenance work order has been used to illustrate the flexibility and advantages of agent-oriented programming.

Many functions within a substation can be performed more efficiently if all the substation data is collected from and shared among intelligent electronic devices (IEDs). Gathered measurements and apparatus statuses can be processed by (local) substation computer(s). Processing includes data consistency checking, switching sequence monitoring, predicting switching outcomes, etc. Processed data may be used locally and/or communicated to remote sites (neighboring substations and/or control centers). Substation data integration is facilitated by existence and appropriate connection of IEDs. The paper presents an approach to implementation of substation data integration and information exchange. The emphasis is on the utilization of local data redundancy to enhance power system state estimation, especially topology error detection.

For buried gas insulated transmission lines (GILs), a coating against corrosion is absolutely necessary and similar to most other directly buried metallic installations. Active corrosion protection, also called catholic protection, may be added to take care about possible failures of the coating as an additional quality insurance system to the passive corrosion protection. Failures in the passive corrosion protection may occur over the lifetime of the system by outer damage through other earth works or by cracks or voids in the material. Then the active corrosion protection system protects such cracks and voids in the passive corrosion system against corrosion. This article proposes some solutions able to protect the GIL against the corrosion by using both the passive and the active corrosion protection.

This contribution describes a very efficient methodology for the computation of the periodic steady state solution of electric systems with nonlinear components. It combines the advantages of applying a Newton technique for the fast time domain periodic steady state system solution with the application of parallel multi-processing technology based on the parallel virtual machine (PVM) computer platform. A comparison of the computer efficiency between the solution obtained with the described methodology and the conventional sequential computation process is presented.

Wide-area phasor measurements provide a dynamic view of the power system in short-term intervals. The time synchronization and concentration of these measurements opens up a range for wide area applications for protection and control. For each kind of instability, related detection and action schemes can be defined to limit or prevent the system from severe disturbances or even collapses. This paper proposes a novel predictive method for emergency frequency control to be used on such occasions. The proposed method avoids the drawbacks of local underfrequency load shedding schemes, such as delayed response and overshedding, by basing control on synchronized phasor measurements. A single machine equivalent for each power system island including the frequency sensitivity of loads, is computed online using phasor measurements. Using this model the progression of frequency stability after a contingency is predicted and stabilizing load shedding is determined in a co-ordinated way for the supervised area of the power system.
