Modeling and simulation of increasingly complex power systems is becoming more important for design, implementation and validation of power system on-line management. Current special-purpose tools are generally weak in the sense that they are mostly block-oriented and thus demand a huge amount of manual rewriting to get the equations into explicit form. Moreover, modification and examination of their...
This paper presents artificial neural network (ANN) based controller model to simulate the automatic voltage regulator (AVR) response for the transient stability analysis. Two different models are simulated considering single machine connected to an infinite bus (SMIB) to check the response of NN behaviour with conventional controller. Based on simulation results, it is found that NN controller gives...
Voltage instability and voltage collapse are complicated phenomenon which can be influenced by the interactions of all power system components. This paper presents an approach for optimal coordination of static Var compensators (SVCs), transformer under load tap changers (ULTCs) and load shedding to improve voltage performance following disturbances and also to ensure a desired amount of post-transient...
Power system dynamic stability includes two problems: power angle stability and voltage stability. For the former, the best way is to install power system stabilizer (PSS) on the key generator groups, and for the latter, however, Flexible AC transmission systems (FACTS) devices such as static var compensator (SVC), static compensator (STATCOM) and so on are the popular methods. PSS can effectively...
Voltage instability impacts power system transfer limits and its reliability. This paper presents an approach to determine a voltage control scheme based on the model predictive control (MPC) theory. MPC is used to develop an optimal control strategy, consisting of a sequence of amounts of the shunt capacitors to switch. The resulting control strategy prevents voltage instability and maintains a desired...
The nonlinearity arising from parasitic parameters in a boost converter is investigated in this paper. It is shown that this nonlinearity can cause a serious instability problem for boost converter control. The nonlinearity makes robust controller design difficult due to sensitivity to disturbances. Static and dynamic voltage collapse is studied. Non-iterative formulae are derived using the bilinear...
Control designs based on geometric feedback linearization (GFL) and the so-called direct feedback linearization (DFL) technique for power system stability control are presented and compared. The physical integrity of the state space description of a classical single machine infinite bus (SMIB) power system model is preserved with the application of DFL in designing a robust excitation-voltage regulating...
