NEM Web Offer System (WOS)

HARD software has developed a web based bidding system for the Australian National Electricity Market (NEM) known as WOS. Using the WOS a generator, retailer or Market Network Service Provider (MNSP) can offer plant prices and availabilities into the NEM and create a complete and verifiable database record of offers, acknowledgments and rejections including audit trails that record all significant user actions.

The system is a true web client server application with no client side requirements other than the use of a standard copy of MS Internet Explorer (5+). The system is designed to provide a high reliability, high availability system than can incorporate multiple application servers and replicated databases than can operate successfully as a connected system or can operate individually and then synchronise when connections have been restored. Encrypted operation can also be supported using SSL (with or without client certificates) so that the web offer system could potentially be used over the internet and provide a widely available tool with the confidence that security can not be compromised.

Further details of the HARD software Web Offer System can be found here.

A full working implementation of the WOS with simulated NEMMCO offer processing is available on this website at for evaluation and training. Click here to access the WOS demonstration system.

Trading Online Data(TOD) system

The HARD software Trading Online Data system (TOD) provides a source of data and an infrastructure upon which tasks that require energy market information, such as marking contract positions to market and trader summary screens, have a central and controlled source of data. The system consists of a database schema and an service that downloads contract swap, option and cap quotes from Reuters systems (eg. TFS, SFE, PREBON & NGES), IGES forward curve, actual trades and AFMA revaluation spreadsheets, interprets the information and stores the results in a RDBMS database structure. Through this organisation of the information, it is possible to write applications to query the database and retrieve all market data that is relevant for any particular time period.

GNU Linear Programming FAQ available here!

HARD software now maintains the Frequently Asked Question (FAQ) list for the GNU Linear Programming Kit (GLPK). The GLPK package is a set of routines written in ANSI C and organized in the form of a callable library. This package is intended for solving large-scale linear programming (LP), mixed integer linear programming (MIP), and other related problems.

The GLPK package includes the following main components:

• implementation of the simplex method,
• implementation of the primal-dual interior point method,
• implementation of the branch-and-bound method,
• application program interface (API),
• GNU MathProg modeling language (a subset of AMPL),
• GLPSOL, a stand-alone LP/MIP solver.

The GLPK FAQ can be download for free in either text, DocBook or PDF formats.
