Load frequency control for power system

Xem 1-5 trên 5 kết quả Load frequency control for power system
  • This paper presents an observer output-feedback load frequency control for power systems with uncertain parameters and time delays in communication networks. First, an observer-based controller is designed dependent on only the observer output. Therefore, the conservatism is reduced and the robustness is enhanced.

  • This study investigates load frequency control based generalized extended state observer (GESO) for interconnected power system subject to multi-kind of the power plant. First, the mathematical model of the interconnected power system is proposed based on the dynamic model of thermal power plant with reheat turbine and hydro power plant.

  • With the development of power system interconnection, the low-frequency oscillation is becoming more and more prominent which may cause system separation and loss of energy to consumers. This paper presents an innovative robust control for power systems in which the operating conditions are changing continuously due to load changes. However, practical implementation of robust control can be fragile due to controller inaccuracies (tolerance of resistors used with operational amplifiers).

  • Currently, in Vietnam electricity market, hydropower plants still account for a large proportion approximately 38%. Thus, study on control problems of the hydropower plants plays an extremely important role. Load – frequency control is one of the most significant control problems. Major objectives of such a control strategy are to focus on maintaining the system frequency at a nominal value (50Hz in Vietnam) and the tie-line power interchange at a scheduled value.

  • This paper introduces such two typical controllers based on artificial neural networks, namely ANN-based NARMA and ANN- based MRAC. Numerical simulation results obtained by such two controllers when solving the LFC of a twocontrol-area interconnected hydropower grid have verified the feasibility and superiority of the proposed control strategies.
