- Description
- A solar-based power supply system, such as a
photovoltaic (PV)-diesel-battery system, is a particularly
attractive option for decentralised power supply in southern Africa
where solar radiation is ubiquitous in most countries. Such systems
can make a positive contribution to the sustainability of rural
communities in developing countries that do not have access to an
electricity grid as they address the shortfalls of stand-alone
systems. However, a lot more design effort and expertise is
required for optimising the sizing and operational strategy of the
PV-diesel-battery hybrid system than is required for single-source
systems. Various models are available on the market and in research
groups but the challenge is to customise these to suit local
conditions. This paper presents the development and application of
a simple spreadsheet-based mathematical model for sizing and
performance prediction of a PV-diesel-battery autonomous power
supply system. The model is employed to generate a set of sizing
curves that define the design space for hybrid systems using
dimensionless component size variables, for a specified supply
reliability and diesel energy dispatch strategy. The outputs of the
model reveal several important sizing and operational
characteristics of the systems
