Abstract

This paper proposes a D-STATCOM structure based on a modular multilevel converter (MMC) with the use of FCS-MPC control method for the purpose of compensating reactive power and stabilizing voltage in the distribution grid. The D-STATCOM is effectively used in cases involving non-sinusoidal and unstable voltages, which often occur in the distribution grid due to the effects of unbalanced nonlinear loads and power injection from renewable energy systems. The proposed structure also has the capability of reactive power compensating flexibility in fault conditions to stabilize the grid voltage. In this paper, a new control strategy, which is based on the combination of an outer PI controller and an inner FCS-MPC controller, was introduced. The outer PI controller is used to reduce static deviations in control values and to provide a reference value for the FCS-MPC controller. The inner FCS-MPC controller calculates the optimal switching state for the purpose of reducing the switching frequency of the MMC. The implementation process begins with the construction of a mathematical model and a control model. Simulations were carried out by MATLAB/Simulink to demonstrate the responsiveness of the control algorithm and the performance of D-STATCOM under the conditions of non-sinusoidal and unstable voltages.

Abstract

This study explores the role of bricolage as a strategic mechanism in the entrepreneurial success of MSMEs at Tanjung Penyu Beach, Malang, which has transformed from an agricultural area into a tourist destination. This research addresses a gap in the literature, which has paid limited attention to the application of bricolage in the context of land-use changes and MSMEs adaptation in the tourism sector of developing countries. Most previous studies have focused on bricolage in the context of technological innovation or large-scale businesses, while its role in supporting MSMEs adaptation in resource-constrained regions remains underexplored. Using a qualitative approach through in-depth interviews, this research identifies how MSMEs in the region creatively utilize local resources following the conversion of agricultural land into a tourism site, providing opportunities for farmers to adapt to environmental changes. This research introduces new insights into how bricolage can be used as a flexible adaptation strategy to address changes in the business environment in developing coastal areas. The findings indicate that bricolage techniques enhance product innovation, leverage social networks, and create new value for MSMEs. However, a major challenge is the promotional strategy, which remains limited to local media, hindering the potential to attract more visitors. The study aims to provide new perspectives on how bricolage techniques can help MSMEs overcome resource constraints, innovate, and capitalize on opportunities in a dynamic context. This study offers insights into how bricolage can help overcome resource constraints and adapt to market changes, highlighting the need for more effective digital promotion strategies to enhance the appeal of Tanjung Penyu Beach as a tourist destination and maximize the success of MSMEs in the area.
