Task 11 - PV Hybrids in Mini-Grids
Task 11: PV Hybrids in Mini-Grids.The focus of Task 11 is the operation of PV within mini-grids (defined as the interconnection of small, modular generation sources to low voltage ac distribution systems). These mini-grids may be powered by a combination of PV, wind, micro-hydro, fossil fuel gensets, and other sources, they typically supply multiple users, and, although they can operate autonomously, they may be interconnected with (or be part of) the distribution grid of the local electric utility. This raises issues of system control and coordination, sustainability and the role of local electric utilities in different jurisdictions. The main goal of Task 11 is to promote the role of PV technology as a technically relevant and competitive source in PV hybrid mini-grids. It aims at enhancing the knowledge-base of multi-source power generation systems including PV and associated electric distribution networks. The objectives of the Task are to:
- define concepts for sustainable PV hybrid mini-grids taking into account local factors (specificity of the application, financing regimes, location, others);
- provide recommendations on individual designs (mix of technologies, architecture, size, performances, other) in order to achieve high penetration level of PV as a means to improve quality,
- reliability and economics of electrification systems such as mini-grids;
- assess the potential of technologies to be mixed with PV for hybridisation; and,
- compile and disseminate best-practices on PV hybrid power systems.
The Task 11 work programme addresses technical and non-technical issues to increasing the market penetration and uptake of PV hybrid systems. Technical issues include design options, operational situations and technology mix. This forms the bulk of the work in this Task. Non-technical issues pertain to the social, economic and environmental conditions through which these systems become sustainable.
