Abstract
This paper provides an analysis of cost-efficient reactive power supply in hybrid-systems and mini-grids. Costs of reactive power result from additional losses in the energy converters when reactive power is supplied. The paper presents an improved operation by diversification and distribution of reactive power supply. A significant reduction of operational costs is demonstrated if distributed generators, such as photovoltaic generators and wind turbines, are integrated in the reactive power supply in mini-grids in addition to conventional rid-forming units such as battery units and diesel generators.
