This paper presents an autonomous wind farm voltage controller based on model predictive control. The reactive power compensation and voltage regulation devices of the wind farm include static Var compensators, static Var generators, wind turbine generators and on-load tap changing transformer, and they are coordinated to keep the voltages of all the buses within the feasible range. Moreover, the...
Nowadays, the development of electric vehicles (EVs) is encouraged in China to address the issues about the energy security and the environment. In this study, the impacts of some crucial factors on the total charging load are investigated, such as the charging rate of the charging infrastructures, the battery capacity, the preference of the charging behavior and the penetration level of the charging...
This paper implements recursive least square method with variable forgetting factors (VFFRLS) in local real-time voltage stability monitoring scheme based on the application of Thevenin equivalent model and PMU to reform the existing methods which present weak performance in tracking the time-varying parameters of equivalent model for power system. The selections of variable forgetting factor and...
Nowadays, environmental-friendly electric vehicles (EVs) attract great attention around the world. However, the adoption of EVs will impact the power system greatly. Different from previous work which concentrated on “when to charge”, research on “where to charge” to minimize the impacts on power grid is presented based on the interaction with Intelligent Transportation System (ITS). With the transportation...
The paper describes a new preference method and its use in e-workflow composition based on context-aware. The E-workflow composition is achieved by the evolution of the mobile agent based on the semantic negotiation. The mobile agent use projection-join closure to capture such message situations, the optimization of the e-workflow composition is translated into dynamic services selection with QoS...
