Scientific and technological advance results in a constantly increasing number of first category customers that in the event of input power failures can entail significant economic losses. A promising direction is the development of uninterruptible power systems that rely on renewable energy sources and, above all, photovoltaic arrays and wind power turbines. If energy customers are located near foothill and mountain rivers, it seems economically viable to apply mini or micro-hydro power plants. The paper examines different approaches to UPS topology based on renewable energy sources. Besides renewable energy sources, power supply encompasses some traditional autonomous sources including diesel, gas piston or gas power plants. In addition, the systems provide inputs for connecting an external power system. The paper shows that agrarian production finds it relevant to develop mobile uninterruptible power systems. The authors propose some modes of operation that improve the economic performance of uninterruptible power supply by using rechargeable batteries solely during power conversion from one power source to another. The paper contains proposals developed to improve operational and technical features of uninterruptible power systems through a new topology, modular character of main functional elements and optimization of system structure.
