“…The number of so-called microgrids, i.e., local electrical grids, often equipped with energy storage and renewable energy sources such as photovoltaic panels [1][2][3][4][5][6][7], is growing. These structures mainly cooperate with the power grid, but they can also work in an island mode, i.e., disconnected from the main power grid [1][2][3][4][8][9][10][11].…”

In this paper, the implementation of sliding mode control algorithms for the case of power grid current regulation in a T-type bidirectional inverter system connected via an LCL filter to the power grid is proposed and presented. A mathematical model of such a system has been proposed, which was then implemented in a simulation environment. The method of designing sliding controllers using the Lyapunov method to conduct a stability proof is presented. The article includes a comparative analysis of two sliding mode control algorithms: the classic one, which includes equivalent control, discontinuous part, and proportional reaching law, and the hybrid one, in which the discontinuous part and reaching law were modified.

“…From the beginning of the massive electrical generation industry at the beginning of the 20th century, conventional synchronous generators have been responsible for guaranteeing frequency stability [4], among other tasks within the operation of a power system. However, mainly in weak or islanded networks, synchronous machines do not always have the capacity to respond fast enough to keep the system stable in the face of power disturbances caused by imbalances between generated and demanded power [5][6][7].…”

Analysis of Control Strategies Based on Virtual Inertia for the Improvement of Frequency Stability in an Islanded Grid with Wind Generators and Battery Energy Storage Systems

Rising levels of non-synchronous generation in power systems are leading to increasing difficulties in primary frequency control. In response, there has been much research effort aimed at providing individual electronic interfaced generators with different frequency response capabilities. There is now a growing research interest in analyzing the interactions among different power system elements that include these features. This paper explores how the implementation of control strategies based on the concept of virtual inertia can help to improve frequency stability. More specifically, the work is focused on islanded systems with high share of wind generation interacting with battery energy storage systems. The paper presents a methodology for modeling a power system with virtual primary frequency control, as an aid to power system planning and operation. The methodology and its implementation are illustrated with a real case study.
