The paper presents method and systems improving quality of power produced by renewable energy sources (RES). The power, delivered by RES, is not stable and not easy predictable. Therefore an additional controllable power sources is applied. There are considered three basic topologies of the controllable generating set used as conditioner. There are fixed speed system with synchronous generator, adjustable...
Paper presents features of renewable energy sources (RES) that have unstable nature. Therefore the RES are connected to stiff grid that stabilizes the AC voltage and provides power in case of low level power produced by the RES. The paper proposes to use an adjustable speed generation system operating in common microgrid. The adjustable speed generation system produces high quality AC power with high...
A renewable energy system RES with cooperation of diesel driven autonomous doubly fed induction generator is presented in the paper. The analysis takes into consideration the power system, where the main power source is a variable speed diesel engine, which operates in full range of power consumption. The RES source is used for diesel engine fuel reduction. The paper presents power distribution between...
