Introducing LMPsimTM: A Modern, Rigorous Approach to the Simulation of LMP Energy Markets (Fall 2005) LMPsimTM represents a new approach to the simulation of LMP-based Energy Markets. Specifically, it includes a rigorous solution of market mechanics that will enable a strong fundamental analysis component to be included within price forecasting. This "engine" has been embedded within a modern software architecture that allows for maximum usability, flexibility and extensibility. LMPsim also represents the first true integration of a market engine with a network application - Siemens PTI's PSS/ETM - thereby providing an essential, fundamental layer required for LMP analysis. A further core principle of the design is to allow for ease in the management of the large amounts of data inherent to this form of simulation. For the complete article, click below.
Simulation of Load Growth in Medium Voltage Networks with SINCAL Network calculation tools since many years are able to simulate a load flow situation - that means the distribution of loads, voltages and currents - throughout a set up network, but for a long-time-network-planning it needs more. To make decisions for e.g. the next 10 years, the planner has to take into consideration the life-cycle of network elements as well as the load development in the network. Especially in medium and low voltage networks high efforts are laid in getting data for load increase. Basis for this could be the loads in the history or forecasts based on socio-economic facts like population development, income, type of houses, religion, education etc. Simulation of scenarios throughout a defined time period, with evaluation of network restrictions during the change of network configuration and load situation, cost the engineer a lot of time during his network planning activities.

PTI - 35 Years in Perspective In August 1969, Power Technologies, Inc. (PTI) was formed by a group of seven engineers with a broad range of power industry-specific expertise. This expertise enabled PTI to tackle a wide variety of consulting opportunities in power system planning, operational economics, corporate modeling, dynamic performance, transients, transmission line design and reliability analysis.

MUSTTM (Managing and Utilizing System Transmission) - an Overview The development of MUST started in 1996 to address the emerging needs of the de-regulated electric power industry. It began as a customized software for a group of electricity companies in southern US, with significant input from these companies to the program development direction and features. The initial objectives were to enable these companies to:

PSS/ETM - the World's Standard in Transmission Planning Software Rev 30 of PSS/E, released in the 3rd quarter of 2004, pushed the capabilities of PSS/E to a new level. First and foremost is the new interface. Replacing the old homegrown interface for Load Flow is a new Windows compliant interface, bringing many of the features and functionality of the standard Windows programs you use in the rest of your work to PSS/E. This includes a customizable workspace, toolbars, copy and paste capabilities between applications and more. In addition to these interface features, the underlying PSS/E analysis engine continues to be improved upon. Buses numbers now support 6 characters and name lengths have been increased to 12 characters. Faults calculations are now done in double precision. Several new contingency events are now recognized in the AC Contingency Calculation solution (ACCC). DC line, FACTS device and auxiliary-signal dynamics models have been "table-ized", removing the need to use CONEC and CONET for these models. A MATLAB-Simulink interface with the Dynamics portion of PSS/E was introduced as well. Using this interface, engineers can design excitation systems and turbine-governors in MATLAB and then use these same models in their PSS/E dynamics runs. Some other items of note in PSS/E Rev 30 are described below. For more information, click below.

PSS/ODMSTM Update and REV. 5.0 Release The CIM1 and GID2 integration platform offered by the Siemens PTI's PSS/ODMSTM product line continues to expand. Recent installations have included developing additional CIM/GID adapters for engineering software applications, and extending the PSS/ODMS adapter to exchange network topology, as well as line design, impedance data, and rating data across the enterprise. In addition to these developments, PSS/ODMS' Model On Demand (MOD) and Historical Case Builder modules have also been extended and improved. For more information, click below.
The DENA Study - a Short Summary The DENA study on planning the integration of wind energy (land and offshore) into the German grid up to 2020 was published on February 23, 2005. Our Network Analysis and Consulting Department has devised technical solutions particularly for the connection of large offshore wind farms to the nodes of the transmission networks operated by EON and RWE. For distances between wind farms and feeder nodes on land of up to 150 km, high-voltage AC transmission concepts employing suitable submarine cables have been preferred. Since the transmission capacity of a three-conductor submarine cable is limited to between 240 and 360 MVA (depending on the voltage level), the number of cable routes to land to carry the 18.7 GW of power projected for 2020 would be between 70 and 100. In order to avoid such a large number of cable corridors, a system model has been proposed (Fig. 1) which incorporates 4 collecting stations out at sea and transmits the power via high-capacity, gas-insulated conductors (GIL).
