VSG Frequency Regulation Strategy for Adaptive Model Predictive Control
Authors: Sun Shida , Liu Tongliang , Deng Yinxi
Published: March 2024

When the active power of a Virtual Synchronous Generator (VSG) is unbalanced, the frequency will fluctuate significantly. Based on this, this article proposes an adaptive model predictive control method. By introducing a hyperbolic tangent function to construct an adaptive moment of inertia that includes frequency change and frequency change rate to provide the inertia for the island microgrid system, and the predicted model is updated in real-time; At the same time, model predictive control is used to calculate the optimal power reference value of VSG, strengthening the power support of VSG. The results indicate that under joint control improves the frequency regulation capability of VSG units and further enhances the system frequency performance, and the frequency deviation reduces from 0.15Hz to 0.05Hz, and the frequency change rate reduces from 0.58Hz/s to 0.5Hz/s. It is proved that the proposed control strategy can effectively suppress the maximum frequency offset and maximum frequency change rate during power fluctuations.

Public Sector Budgeting in Poland: Challenges and Opportunities in a Changing Economy
Authors: Jarosiński Krzysztof
Published: March 2024

This paper examines the challenges faced by Poland's public sector enterprises and organizations as they manage budgets during the country's transition to a market economy. It investigates how traditional budgetary principles interact with new economic development concepts, drawing on development economics to understand the unique context of Poland's systemic shift.  The study analyzes empirical data and public finance trends, arguing that maximizing tax revenue through higher burdens is counterproductive. Specifically, the paper explores how escalating tax burdens on public sector units can stifle economic growth and contribute to the expansion of the shadow economy. Instead, the paper proposes a focus on rational and efficient resource allocation within the public sector as a means to bolster budgetary revenues without hindering overall economic development. This study offers valuable insights for policymakers and researchers interested in understanding the complexities of public finance management within transitional economies.

Empowerment of Copra Farmer Group using E-Commerce
Authors: Batmetan Johan Reimon
Published: March 2024

Copra farmers in the village of Pondos, South Minahasa, are copra farmers who produce copra traditionally. So far, copra production has only been sold to existing middlemen and at a price determined by the middlemen themselves and regardless of the price of copra in the market. This causes the copra farmers to lose a lot of money because the farmers sell them at too low a price to existing middlemen or brokers. On the other hand, copra farmers do not have the skills to use e-commerce information technology so farmers are increasingly disadvantaged by middlemen. Another problem is that the market reached by copra farmers is only limited to the West Amurang area and is very limited, so the copra production produced by the farmers becomes abundant in the market. This is used by middlemen to speculate on prices so that copra prices fall and are very cheap among farmers. The solution that is trying to be offered is to provide training and assistance on the use of information technology, and e-commerce to copra farmers so that they are able to improve their ability to use e-commerce for marketing copra commodity products. With the increasing ability of copra farmers, they can use it to get copra prices that are in accordance with market prices, they are able to sell copra products through existing e-commerce and are able to reach a wider copra market. The method used to conduct training for copra farmers is a quantitative method of measuring the ability and income of farmers before and after the implementation of assistance. With this service program, it is hoped that copra farmers' skills and abilities in using e-commerce will increase and the income of copra farmers will increase because they are able to sell at market prices and can be monitored in real-time. The expected result is that copra farmers can reach a wide and large market for copra commodities so that they can increase farmers' copra production
