Summary: The microgrid is a new trend in modern power systems, consisting of controllable power sources, storage, and loads. A hierarchical control scheme composed of multi-agents is established to regulate and synchronize the interaction of these components. Communication delays in transmitting control signals can lead to deteriorated control performance, but this paper proposes novel multi-agent moving average estimators to mitigate the effect of latent communication links and establishes a hierarchical control scheme incorporating these estimators for accurate system values during delays. Mathematical models, simulation studies, and experimental verification demonstrate the efficacy and superiority of the proposed control scheme in comparison with conventional methods.

Summary: This study introduces a PLL algorithm for detecting positive-sequence and negative-sequence grid voltages in three-phase systems, using an adaptive filter to accurately track the fundamental component of the grid voltages even in the presence of harmonics. Comparison with other similar structures shows high immunity of the introduced PLL to power quality disturbances, with a drawback of slow dynamic response due to the adaptive filter.

Summary: This paper presents a comparative analysis of a static synchronous compensator (STATCOM) based on battery energy storage system for stability enhancement of offshore wind power plants. The results show that the grid-forming control offers evident stability margin and damping to the WPPs, especially in weak grids, superior to the grid-following STATCOM. The small-signal models and comparative analysis are validated through electromagnetic transients simulations.

Summary: In recent years, technical progress has led to the conversion of traditional electric power systems into Smart Grids, triggering a global revival in the overlooked field of power quality (PQ). Due to the high costs associated with installing PQ monitors, it is not feasible to install one on each grid busbar. Therefore, grid operators need to determine the best cost-benefit scenario for monitor installation, achieving maximum observability with a limited number of analyzers.

Summary: This study models a biomass fluidized bed gasification system, which is one of the most effective ways to produce energy from biomass resources and wastes. The turbulence phenomena, such as flow turbulence, chemical fuel reactions, and energy and momentum exchange between solid and gas phases, are taken into account in the research. A computational fluid dynamics case study model combining equations with comprehensive geometry is used and validated against published operational records. The results show that the model accurately predicts solid particle distribution, velocity, turbulent flow viscosity ratio, temperature distribution, and the molar fraction of constituent elements in the synthesis gas.

Summary: In traditional grid-tied photovoltaic installations, bypass diodes are used to short-circuit shadowed PV modules, resulting in a loss of potential energy production. This loss can be recovered by using a dc-dc converter (micro-converter) coupled to each PV module and operating at the maximum power point (MPP). This paper proposes an enhanced control algorithm for the micro-converters to provide a smooth start-up operation and safely transfer power from the PV units to the grid.

Summary: This article investigates the influence of nonlinear behavior of photovoltaic (PV) sources on the dc voltage regulation of single-stage single-phase grid-connected inverters. The analysis reveals two issues: undesired strong coupling between regulation transient performance and PV source operating point, and possible instability arising when the PV source operates on the left-hand side of its maximum power point (MPP). To solve these problems, the idea to add the PV power feedforward signal to the output of the dc voltage controller is proposed, resulting in improved PV voltage regulation performance and stable dc voltage control dynamics.
