摘要
Abstract
To achieve voltage control and improve the power supply capacity, a distributed algorithm for voltage control in the microgrid is proposed with active power injections provided by DGs. First, for the property of line impedance in the low voltage microgrid, the relationship between voltage and active power is analyzed. Then, a communication link is established according to the system structure, and the bus voltage that exceeds the upper and lower limit is initiated by computing the active power needed. Based on the local information, the bus voltage is corrected by a parametric state transition matrix with the consideration of active power capacity limits. Eventually, the active power of DGs is coordinated and distributed through the algorithm to achieve voltage control collectively. Simulation results show that the proposed algorithm can effectively achieve voltage control and decrease voltage deviation, so as to improve the voltage quality.关键词
