Embedded generators connected at Low voltage (LV) networks include many sources; by far most embedded generators are PV -inverters. The presentation will focus on LV connected embedded generators and the issues it creates in the SA environment.

Connecting embedded generators to utility grids presents risk to the maintenance staff of utilities. The statutory responsibility of ensuring safe electrical installations lies with the “user or lessor” of an “installation”. This is the customer after the point of supply and the utility before the point of supply.

Embedded generators can have severe detrimental effects on LV and MV network. NRS 097-2-1 and NRS 097-2-2 specifies the technical requirements and grid compatibility levels that needs to be met by LV embedded generators as well as the compatibility levels applicable to the grid connected embedded generators.

The ability of the Distribution LV and MV network to absorb energy generated “in the reverse direction” is limited and much less than the ability of the grid to deliver energy- some of these aspects are dealt with in NRS 097-2-3 and will be expanded on.

The technical management of the grid is a complex process, segmented into many disciplines. When an Embedded Generator application is received by a utility, the internal processes engages with the respective departments, this process will be discussed and explained.

Mr Mobolaji Bello, Senior Engineer, Eskom Holdings SOC Limited

Dr Hendri Geldenhuys is an Electrical Engineer, employed by Eskom as Corporate Specialist in the Technology Division. He works across organisational boundaries on technical-business issues mostly related to the Distribution business of Eskom. This ranges from business processes and strategies for renewable energy integration, the evolution of smart grid especially with respect to engineering applications thereof, to hard technical issues such as insulation coordination design, MV system design, network safety issues and lightning protection. Cost effective technologies for electrification and off grid electrification solutions. Hendri focuses on technology innovation in this environment and most of his work involved the development of technologies and improving existing technologies.

Mobolaji Bello holds BEng(Hons) and MScEng degrees in Electrical Engineering, MSc in Technology Management and Innovation and also a BSc(Hons) degree in Industrial and Systems Engineering. He is a Network planning specialist within Group Technology division, Eskom Holdings SoC Limited, South Africa; and is involved in the standardization on the grid connection of renewable generation to Eskom networks. He is the author/co-author of several refereed journal/conference papers and scientific articles. He is a Senior member of IEEE, a Chartered Engineer (CEng), and an International Professional Engineer (Int. PE) with the Engineering Council UK.
