Nowadays, power quality (PQ) issues are gaining considerable attention to both electrical utilities and end-users as they are causing significant financial losses to industrial customers. Among PQ issues, voltage sag and swell are the most important and frequently occurring problems for sensitive load. Voltage sag/swell can be mitigated using a distribution static compensator (DSTATCOM), which is fast, effective, and flexible custom power device. Its performance mostly depends upon the designed control scheme for the switching of voltage source converter (VSC). In this research work, a fused control scheme based on second-order super twisting algorithm (STA) and sliding mode control (SMC) for VSC of DSTATCOM is developed, that can effectively eliminate the effects of voltage sag/swell as well as compensate active and reactive power in distribution system. STA along with standard SMC is used to eliminate the chattering effect which is the drawback of SMC alone, while keeping its other properties such as robustness, faster response time, and insensitive to load variation. The proposed control scheme for DSTATCOM is simulated on SimPower system toolbox of MATLAB/Simulink. Both linear as well as nonlinear loads have been considered for the purpose of static and dynamic analysis. Simulation results show that the super twisting sliding mode control (STSMC) for DSTATCOM can effectively detect and correct voltage sag/swell and compensate active and reactive power within 2.5 milliseconds as per semiconductor processing equipment voltage sag immunity standard for sensitive load (SEMI F-47 Standard). Total harmonic distortions (THD) measured in all simulated cases is found to be less than 5%. The frequency response analysis shows good stability properties of developed system.

“…2The term grid flexibility will be used in the remainder of this paper to refer to all ‘non-costly’ TSO resources acting on the properties of the transmission network rather than on the power injected/absorbed by the network users. In addition to phase-shifting transformers (PSTs), this term generally encompasses transmission switching [16], dynamic line rating [17], static VAR compensators (SVCs) and thyristor-controlled series compensators (TCSCs) [18], etc.…”

This paper advocates for a progressive rethinking of the day-ahead/intra-day power system security management practice in the low-carbon energy transition era. As a starting point, the need for coordination between multi-area transmission system operators in order to efficiently exploit the value of grid flexibility towards operating the low-carbon, multi-area power system securely and economically is emphasized. On this basis, the core proposal of this paper is the adoption of a new approach to day-ahead/intra-day multi-area power system security management, inspired by the principles of cooperative game theory. The proposed approach relies on counterfactual analysis to evaluate the (positive and/or negative) impact of each distinctive control area to the common security of the multi-area system, thus providing clear economic incentives to achieve the required coordination. This proposal is not a marginal approach and notably facilitates the integration of more detailed physical modelling (including the non-convexities of the power system) in the inter-TSO settlement of the multi-area interconnected system security management cost. The proposed framework allows some level of subsidiarity and the definition of hedging products to cover ex-post costs. Further from the blueprint of the proposed approach, the paper presents a demonstrative implementation in the context of static N-1 security management and discusses prominent research and development pathways in order to progressively put such vision into practice. This article is part of the theme issue ‘The mathematics of energy systems’.
