Resonance Attacks on Load Frequency Control of Smart Grids

The problem of secure load frequency control of smart grids is investigated in this paper. The networked data transmission within the smart grid is corrupted by stochastic deception attacks. First, a unified Load frequency control model is constructed to account for both network-induced effects and deception attacks. Second, with the Lyapunov functional method, a piecewise delay analysis is conducted to study the stability of the established model, which is of less conservativeness. Third, based on the stability analysis, a controller design method is provided in terms of linear matrix inequalities. Finally, a case study is carried out to demonstrate the derived results.

Load Frequency

One of the efficient control methods is the model predictive control(MPC) that calculates appropriate system inputs to reduce the difference between the desired and the system predicted output. One of the important applications of this strategy is in power grids for load-frequency control and power balancing. Different architectures of MPC are applied in large scale structures such as power grid. In this paper a feasible cooperation based MPC(FC-MPC) controller has been used as a suited solution to control problem with relatively strict constraints. Also it can be used as one of options for control system of smart grids in future. In this paper, a power grid with 4 control zones has been chosen as a case study. The simulation results indicate the superior performance of the discussed control method in comparison with the traditional control of load- frequency.

Smart Grid System

In the recent era, the need for modern smart grid system leads to the selection of optimized analysis and planning for power generation and management. Renewable sources like wind energy play a vital role to support the modern smart grid system. However, it requires a proper commitment for scheduling of generating units, which needs proper load frequency control and unit commitment problem. In this research area, a novel methodology has been suggested, named Harris hawks optimizer (HHO), to solve the frequency constraint issues. The suggested algorithm was tested and examined for several regular benchmark functions like unimodal, multi-modal, and fixed dimension to solve the numerical optimization problem. The comparison was carried out for various existing models and simulation results demonstrate that the projected algorithm illustrates better results towards load frequency control problem of smart grid arrangement as compared with existing optimization models.
