“…In addition to minimizing THD or the fundamental component of the filter current a set of different load current harmonics is the main focus of the system control. There is a delay in the time when a fresh set of switching angles generated from the optimizing technique is the detection of a harmonic current change and application [150][151][152][153][154].…”

Renewable energy sources such as photovoltaic (PV) and wind energies are integrated into the grid due to their low global emissions and higher power conversion efficiency techniques. Grid-connected inverters are the core components of distributed generation networks. However, several harmonic current and voltage variations affect the performance of circuits in grid-connected networks. These issues can be easily resolved using passive filters, static vector generators, and dynamic energy filters (APFs). In higher-level units, the cost, dimensions, and weight of passive filters increase proportionally. The purpose of this research is to evaluate advanced APFs for reducing power switches and grid-connected weight, cost, and scale. Several studied APF inverter topologies, including single-phase, three-phase AC–AC, back-to-back, and common parameters, have been considered. Cost-effective solutions such as PV-based transformers based on APF, fewer inverters, multiple and multifunctional inverters, and wind-assisted conversion systems have been studied.

“…In order to realize the global dynamic interactive regulation of microgrid SNLSC, a microgrid model is built in this paper, including microgas turbines, small hydropower, electric vehicles [22], solar energy storage power plant [23], wind farm and cooling, heating and power storage model [24], as shown in Figure 3, and the model parameters [25] are shown in Table 1. Among them, wind farms and electric vehicles are involved in only one FM, PV is simulated with 24-hour light intensity [26] adding a small perturbation, and unit parameters are shown in Table 2.…”

The efficiency of on-site consumption of new energy and the economy of dispatching strategy for that in modern microgrids are increasingly concerning, which are closely related to the microgrid control model with source-load uncertainty. To this end, this paper proposes the multiagent hierarchical IQ (λ)-HDQC regulation strategy to realize the source-load-storage-charging collaborative control of the microgrid model with high-permeable new energy. The first layer adopts the IQ (λ) strategy, which avoids the overestimation and underestimation problems of traditional reinforcement learning by the coupled estimation method. The second layer adopts the HDQC allocation strategy, which solves the problem of low utilization of new energy in the proportional allocation method and improves the adaptability of the regulation strategy in the complex stochastic environment. The interaction of the two-layer strategies realizes the source-network-load-storage-charge global dynamic interactive regulation of microgrids. Indicators of energy efficiency are constructed in this paper to measure the simulation results. And the superiority of the proposed strategy is verified through the simulation results of the microgrid system.

“…Three-phase power imbalances could happen in distribution networks as a result of high EV charging demand. The imbalances become problematic with the rising number of EVs in the future and could be alleviated with coordinated charging strategies [7]. -As power systems are restructuring, the energy transaction between EV (via charging stations) and distribution network has become a key development.…”
