Evaluation of stand-alone inverters for remote applications
A stand-alone or autonomous system that supplies ac electric power to loads in remote applications is a mini-utility. It requires all the basic elements of a large system. These basic elements are an energy source, a storage medium, and a power conditioner (inverter) with built-in or external control and distribution capabilities. The source for an autonomous system will probably be one of the renewable sources of energy such as wind or photovoltaics. The electrical storage will be a battery bank. The inverter, with the variable energy source and the energy storage sized for the autonomy of the system, must be capable of converting the energy and supplying controlled ac power to the loads on demand and in a safe, efficient, reliable, and compatible manner. This paper describes the evaluation of several small (typically 1-kW) stand-alone power conditioners. The purpose of these evaluations was to determine the dc input and ac output characteristics of the power conditioners, the control algorithms, and the compatibility and interactions of the power conditioners with the complex loads most likely to be used with the stand-alone or autonomous systems.
