“…Traditional power system stabilizers (PSSs) have been widely studied to solve the problem. However, PSSs based on local measurements are not always effective, due to the lack of global observability, mutual coordination and placement flexibility [1][2][3][4][5]. Fortunately, the new technology of wide-area measurement system (WAMS) offers the potential of global damping controls to ameliorate the situation [1][2][3][4][5].…”

Fortunately, the new technology of wide-area measurement system (WAMS) offers the potential of global damping controls to ameliorate the situation [1][2][3][4][5]. Several wide-area control schemes have been reported, such as the remote feedback controller [5,6], the multi-loop PSS [4,7], the H∞-approach-based supervisory-level PSS [8] and FACTS controllers employing global signals [9,10].…”

“…Using the original system model (8) to carry out robust control synthesis is a little time-consuming, so we use balanced truncation technique [11] to reduce the original 26-order system model to an 8-order system model. Model singular values of original and of reduced model are shown in Fig.…”

This paper presents a new strategy for the design of wide-area robust controller (WRC) to damp the inter-area mode oscillations of power systems. Utilizing both local and remote non-delayed signals as controller inputs, mixed H 2 /H ∞ outputfeedback design procedure is applied. Considering the specific power system construction, the remote feedback signal is chosen to associate with H 2 performance which is useful to handle stochastic aspects; whereas the local signal is chosen to associate with H ∞ performance which is primarily concerned with model uncertainties. The feedback gain matrix is obtained through solving a family of linear matrix inequalities (LMIs). Experiments on a 4-generator test system demonstrate the effectiveness of the new controller and robustness with respect to variations of the system operating conditions. The results are also compared with the conventional PSS damping control.

Este trabalhoé dedicadò a minha esposa Patrícia, ao meu filho João Pedro, aos meus pais Izabel e Nelson e aos meus irmãos Lívia e Gustavo.iv AGRADECIMENTOS A minha esposa Patrícia pelo amor, companheirismo, dedicação, compreensão, paciência, garra para cuidar do nosso príncipe em minhas ausências, por entender minhas ausências diárias, pelo apoio e carinho essenciaisà minha tranquilidade para mais essa vitória.Ao meu príncipe João Pedro por receber o papai todos os dias com um sorriso lindo e reconfortante, por dar sentido a vida do papai e da mamãe, e por compreender, ainda que com poucos meses de vida, que minhas ausências diárias tinham oúnico propósito de trazer conforto e aprendizadoà nossa família. The proposed methodology was evaluated by two kinds of data. In a first kind, the signals were simulated. For this purpose, it was used the Power System Toolbox software (PST). In the second kind, it was considered field data obtained from PMUs installed at low voltage in Brazilian universities in several states. Considering the stochastic nature of the data, the proposed method identified the dominant modes present in the simulated ambient data of the test system accordingly, both in situations in which the frequency and damping of the mode were fixed, as in situations in which the mode parameters varied throughout the period of simulation. In the case of the field data, the results identified the presence of dominant oscillation mode in the frequency range between 0,2 Hz and 0,4 Hz. This is an inter-area mode, characteristic of the Brazilian National Grid. Therefore, in both kinds of data, the proposed methodology was appropriate to identify dominant modes from ambient data.vii
