Power systems analysis software application

TNEI has been working on innovative projects since the company was founded. We have supported the development of nine NIC and LCNF projects which were successfully funded by Ofgem and have been involved in the delivery of seven of these types of projects. Often, this involves an innovative application of our power systems analysis software, IPSA 2.

For example, TNEI’s software team was engaged by WPD as part of their FALCON LCNF project, which investigated new techniques for managing 11 kV networks. IPSA 2 formed the core of a simulation tool which was developed within the project. This tool modelled the impact on the network of ‘smart grid’ technologies like Dynamic Asset Rating, Energy Storage and Demand Side Management, alongside traditional reinforcement methods. As part of the project, many new features were added to IPSA 2, including profile (or time of day) analysis, reliability analysis (to calculate customer impacts) and voltage unbalance analysis.

The modelling capability of the power sector will need to be enhanced in the future as networks change and new technologies emerge. TNEI actively develops new features for IPSA to ensure that the industry has the tools it needs to deal with these challenges.
