Useful Links

A number of our collaborative projects have websites which are within the public domain.

If you are interested in the issues surrounding distribution system losses and loss reduction, and the active management of networks, you may be interested in the Kestrel project.

We are tackling the key issues surrounding the connection of alternative energy and renewable energy sources to existing power networks through our involvement in the Zefal consortium.

If you are interested in the future of energy networks, and how they will evolve to meet the challenges created by the sustainability debate, you can find out more about our work at the FutureNet and FlexNet websites.

Poster of Application of Load Profiling in Planning and New Connections

This poster is introducing a novel approach to validate new connection requests to distribution networks based on the knowledge of existing customer behaviours (load profiles). This work was part of the Distribution Network Visibility tier 1 LCNF project which PPA Energy undertook in a consortium with UK Power Networks, Capula and Powersense. 

CIRED 2013 Paper – IDENTIFICATION AND VISUALISATION OF CHANGES

This paper outlines the analytical and graphical techniques being used to classify secondary substation load profiles and identify when changes occur.  Please view the complete Paper here.

Prospects for the African Power Sector
This paper, published by International Renewable Energy Agency(IRENA), focuses on scenarios and strategies for African project. It compares two scenarios-the Reference Scenario and the Renewable Scenario. For more details, please download the report here.
Dynamic governor model development for grid code compliance
This article was written by Dr Graeme Chown and Rahul Desai from PPA Energy, Mike Coker, Eskom and M-Tech experts. It describes the process followed for the development of governor models for four Eskom coal fired power stations.

Avoidance of MV Switchgear Failure Case Studies of On-line Condition Monitoring

This paper considers, through a series of practical case studies, the avoidance of major incidents through the targeted use of on-line condition monitoring of MV indoor switchboards. A technique to pin point the location of partial discharge (pd) using time of flight measurement techniques is discussed.

Southern African Power Pool - ancillary services

This presentation was given to the IEEE PowerAfrica Conference in July 2007.  Co-authored by PPA Energy and SAPP senior team members, it discusses the proposed structure of ancillary services for the Southern African regional market.

Controlling Losses in Electricity Businesses

PPA Energy is involved around the world in assisting clients to control and manage losses in electricity businesses, whether commercial in nature (through billing/metering issues, fraud, illegal connections etc.) or technical (due to system design and configuration etc.).  THis paper provides an overview of our thinking in this area.

Assessing the Contribution of Renewable Generators

A key issue for network operators is understanding how renewable generators such as wind farms contribute to the overall security of the power system, given that they are dependent on external conditions and cannot necessarily be dispatched to meet changes in load.  PPA Energy undertook this important study to understand how different types of generators should be assessed.
