This paper proposes a hybrid ac/dc micro grid to reduce the processes of multiple dc-ac-dc or ac-dc-ac conversions in an individual ac or dc grid. The hybrid grid consists of both ac and dc networks connected together by multi-bidirectional converters. AC sources and loads are connected to the ac network whereas dc sources and loads are tied to the dc network. Energy storage systems can be connected...
Addition of Renewable resources in a power system will have significant impact on power generation. Generation Companies (GenCos) characteristics will change according to the availability of new resources. Wind power as a representative and the most common-used renewable energy resource is studied in this paper. Although wind speed is simplified and represented by multistate models, load point reliability...
In a power system with high wind power penetration, reserve allocation is a major problem of system planning and operation due to the uncertainty and fast fluctuation of wind speeds. In order to achieve long term sustainable solution for electricity supply, the impacts of the installation of wind farms on system reliability have to be carefully studied. This paper describes the impact of installation...
