Exploring the Dynamic Process of Interactive Control: An Application of a Computational Simulation

The objective of this study is to examine how interactive control (IC) influences emergent strategies. The aim of IC is to make a new strategy emerge by directing the organizational attention to a strategic uncertainty. In the process of IC, individuals are encouraged to search for new opportunities and threats, repeat experiments with trial and error, and engage in dialogue for innovation. Such micro-level attempts, which are often contingent and continuous, are put together at the macro-level to emerge a new strategy, called a dynamic process of IC. This study explores the dynamic process of IC by focusing on the mutual relationship between the micro-level activities and the macro-level phenomena that occur in the organization. To do this, we used a computational simulation method, agent-based modeling, to make the process of IC observable. Our simulations illustrated repetitive interactions at the micro-level, and a strategic pattern emerged at the macro-level. We discussed the simulation-based results to suggest several implications: the micro-macro loop in the dynamic process of IC, the effect of the high intensity of IC, tension management, and strategic uncertainty. Finally, limitations of this study and future research were addressed.

An Improved Fast Detection Method on Subsynchronous Resonance in a Wind Power System With a Series Compensated Transmission Line

Subsynchronous resonance (SSR) occurs mainly in series compensated transmission line connected to the wind power system. This phenomenon (SSR) can lead to electrical instability and potential turbine generator shaft failure. Thus, the protection system is an essential part to avoid the harm of SSR. In this paper, an improved fast detection method is proposed to detect the SSR phenomenon in a very short time. It consists of two stages; first, the positive or negative half-cycle time of each cycle of voltage signal is detected based on four steps, namely, signal conversion, comparison, integrator, and sample and hold; second, the obtained time is compared with the damping and trip threshold values, and the best action is determined (addressing or trip) based on the value of half-cycle time. The effectiveness and superiority of the improved fast SSR detection method are validated at different compensation levels and compared with the traditional method and subsynchronous oscillation relay (SSO). The simulation results prove that the improved method is more efficient in all types of SSR phenomenon; induction generator effect (IGE), control interactions (CI), and torsional interaction (TI) at different compensation levels. In addition, a comparative study among these three types of SSR with the proposed method is carried out, and the obtained results show that the CI is a suitable type with the proposed method.
