“…Differences of voltage magnitude and phase between the point of common coupling (PCC) on the island side and the main grid can be obtained by synchronized phasor measurements. Wide-area monitoring based on synchronized phasor measurements is already in use in large power systems (Prioste et al 2011). A dissemination of this technology for generating power plants, including SHP, is expected, making feasible its use for DG control (Best et al 2010).…”

In countries with large hydroresources, generation formed by small hydropower plants may have a significant participation in distributed power generation. Small hydropower plants are connected at subtransmission or distribution level and usually are disconnected after contingencies and islanding. Islanded operation requires adequate system dynamics after disconnection and smooth reconnection. The increase in wind generation and photovoltaic sources requires that utilities consider these sources in islanded operation. In this paper, the design of coordinated controllers for reconnection of distributed generation including hydro-and wind power plants after islanding is considered. The design method is based on constrained optimal control, which allows the design of structured controls such as PI, PID and decentralized. The proposed method is applied to a test system with two small hydropower plants and a wind farm. The results show that the proposed method provides a systematic design approach to ensure smooth reconnection of the islanded network to the main network.
