| Popis: | Renewable energy sources particularly solar energy have a great potential in fulfilling the energy demand in far-off rural areas where providing electricity is difficult from the existing transmission line network of the main grid. Photovoltaic (PV) sources possess stochastic nature either operating standalone or connected to the main power grid. The standalone systems have various issues like voltage fluctuations and power quality which also have an adverse effect on equipment utilizing the power generated from PV sources. Standalone PV systems consist of PV panels, a storage system, and a charge control unit (CCU). To fully utilize the energy generated from PV panels all these components as well as loads must be optimized to provide an efficient operating scenario in microgrids. Required operating condition is achieved by a distributed optimization method with the lower and upper bound constraints in terms of population dynamics of microgrid components. To implement this, a microgrid is considered with 10 Standalone PV systems with residential loads. The analysis shows how power converges to a reference value and provides a stable voltage profile for the standalone microgrid systems in rural areas. |
