Welcome

PSS™E version 31 breaks new grounds in transmission planning by keeping in mind our users' feedback. In addition to bringing PSS™E into a single user Windows® environment (version 31 operates all modules: Power Flow, Short Circuit and Dynamics, under a single windows-based user interface), version 31 incorporates a number of user-suggested features; and  Siemens PTI shall continue its ”user-in-mind” strategy for incorporating further enhancements into the PSS™E software.

A revolutionary concept in version 31 is the introduction of “Scenario Manager” where all files and data for steady state and dynamics studies are brought into one contiguous work space, relieving the user from tracking the large numbers of files of the past. However, it maintains flexibility for that user who may want to customize the scenario area.

Furthermore, Siemens PTI is pleased to announce that version 31 is now compatible with various automation files developed on previous PSS™E versions such as IDEV, IPLAN, etc. and not just .RAW. By simply adding a version number to the start of the IDEV or IPLAN files, the user is able to execute these files directly in PSS™E version 31. This feature was specifically developed to address the requests of those users who had to re-work their automation files with every new PSS™E version.

There are also new optional algorithms available in PSS™E version 31. These include: 1) an enhanced Graphical Model Builder (GMB) and; 2) NEVA Eigen value and small signal analysis that provide a significant upgrade to the existing LYSAN small signal package. Couple these modules with the reliability analysis module that has been integrated from TPLAN into in the base PSS™E steady state module at no additional cost to current PSS™E clients, and our users receive what we believe to be a powerhouse of analytical capabilities required to meet the design challenges of both today's grid and tomorrow's smart grid.

Finally, I like to thank our users, who without their continuous loyalty and support, the new PSS™E era would not have become a reality.

Siemens PTI in Peru to Present Recommendations to Electric Sector Stakeholders

Siemens PTI (in association with Quantum Andes, a Peruvian firm) delivered several presentations last November in st1:place w:st="on">Lima to Peruvian electric power sector stakeholders. These presentations included recommendations with respect to transmission interconnection reinforcement solutions between the central and southern regions of Peru. The recommendations were developed as part of an assignment performed by Siemens PTI and Quantum Andes for Osinergmin (the energy and mining regulatory entity in Peru) entitled “Risk Analysis of the Transmission Interconnection between the Central and Southern Regions.” Among the attendees at the presentations were representatives from the Ministry of Energy and Mines, Osinergmin, COES (the system operator) and REP (a transmission service provider). The presentations also included Siemens PTI's independent assessment of the current transfer capacity between the central and southern regions, and the results of our analysis of the Peruvian regulatory framework for electricity relative to the implementation of new transmission projects.

PSS™E Introduces Next Generation Plotting Package

The ability to display numeric data effectively in a graphical form plays a critical role in both understanding and deeper analysis of the contained information. From traditional line graphs to three dimensional surfaces, a pictorial representation lends itself to easier scrutiny and further investigation.

Competition in Power Production

Successful participation in competitive electricity markets requires strategies that consider multiple time horizons. Developers and operators of power plants must address all time horizons, varying from years to minutes. Strategies must be developed for each of the time scales in the figure below. These include:

• Assessment of the physical and financial viability of a project and the position of that project in the queue of all projects requiring assessment
• Participation in capacity markets where they exist
• Participation in day-ahead markets where they exist
• Participation in the real-time or balancing market
• Real-time operation, performance, penalties, and costs

Exporting PSS™E Results and Data to Excel Spreadsheets

In PSS™E version 31, ACCC, PV and QV analysis results can be exported to excel spreadsheets using Excel Export GUI. This GUI is launched from PSS™E menu Power Flow>Reports>Export to Excel or Start>Program>PSSE31>PSS™E Utilities>Export to Excel.

Risk Assessment of Power Systems with PSS™E

Risk and reliability are the two facets of a measure of the ability of the electric power system to deliver electricity to all points of utilization within accepted standards and in the amount desired. Both terms have the same implication. Higher risk means lower reliability, and vice versa. A general definition of risk is “probability x consequence.” In power systems, this concept can be applied to calculate certain reliability indices such as Expected Unserved Energy (EUE) which is “probability x lost MW” (consequence) and a measure on system reliability from customer point of view.

Training for the Future

Everyone has heard the warnings about the aging workforce in the utility industry. The question is…What are you doing to plan for the future? The number of experienced engineers is shrinking every year and those remaining in the industry are left to carry the load. We need to think outside the box and figure out how to build the next generation by grooming them so that they can step in and do the work.

One of the key elements in creating successful engineers is training. Siemens Power Academy TD has been successfully training power engineers domestically and internationally for over 38 years. We are recognized as a world leader for training in the electric power industry. With our large training portfolio, the Power Academy can be your partner for employee development.
