“…Theoretically, the fifth harmonic current by the harmonic generator injected into power grid should be the sum of the fifth harmonic current absorbed by the PDTF I f5 with the fifth harmonic current remaining in power gird after filtering, i.e., I h5 = I f5 + I s5 . However, due to the influences of fluctuations in power grid and background harmonic current, the sum of I f5 and I s5 slightly deviates from I h5 in the test [27]. When the capacitance of filter capacitor is constant, the control signal of PDTF (approximately 5300) basically remains unchanged.…”

Along with massive applications of power electronic equipment and non-linear loads, harmonic pollutions are becoming more serious than ever. This paper describes a novel electromagnetic coupling reactor based passive power filter with dynamic tuning to quickly eliminate harmony. Firstly, the structure and mathematic model of electromagnetic coupling reactor are presented; secondly, the employed parameters, including electromagnetic coupling reactance converter, primary winding coil, and secondary winding coil are designed based on a stable structure of data; then, the test plat of passive dynamic tunable filter is introduced, as well as the performance test. According to the experimental results, the newly designed electromagnetic coupling reactor can effectively eliminate the harmonies generated by the nonlinear load, greatly reducing the harm caused by harmonics on the grid. By fine-tuning the electromagnetic coupling reactor, the dissonance caused by the change of capacitance and other issues can be effectively solved. Finally, the detailed discussion of this paper is presented, and challenges and new future research are discussed.

“…Furthermore, the research work presented in this paper is a continuation of the work by the authors [14], where a framework for considering nondeterministic polynomial-hard (NP-hard) problem with the cheaper version of the software is needed. Moreover, the global optimal solution in the fastest possible time which is an important issue in real-time application development is achieved in comparison with [14]. In this study, a general CEMS framework with a plug-and-play structure is proposed to minimize the operation cost of H-MG.…”

“…Primarily EMS should be able to satisfy plug-and-play operation particularly in larger H-MGs with different players, as such to the EMS should adapt itself to real-time changes in the type and capacity of generation and storage assets. In this study, a comprehensive CEMS is proposed to overcome the problems discussed above where the plug-and-play operation is provided [14,17]. In this study, single ownership is considered to simplify the market structure and optimization analysis with features like, e.g., plug-and-play type real-time optimal operation.…”

“…Since it is likely to have shortage or excess in power generation anytime during the daily operation of an islanded H-MG, the energy management system (EMS) design should consider this specification. It is also desired for the EMS design to adapt and compensate itself in real-time to any changes in the types and capacity of the generation and storage assets quickly, without any modification in the EMS, in addition, maximizing the operational efficiency (equivalently minimizing the cost of operation), minimizing the emission [5], maximizing the lifetime of assets [6][7][8][9], increasing the reliability of inter-operatability [10,11] or a combination of the above for a multi-objective type EMS [12][13][14][15]. The proposed supervisory controllers for the safe and optimal H-MGs operation are categorized as: central energy management system (CEMS) and distributed energy management system (DEMS), where certain advantages and drawbacks have been comparatively reviewed in [12,16].…”

Real-time energy management within the concepts of home Microgrids (H-MG) systems is crucial for H-MG operational reliability and safe functionality, regardless of simultaneously emanated variations in generation and load demand transients. In this paper, an experimental design and validation of a real-time mutli-period artificial bee colony (MABC) topology type central energy management system (CEMS) for H-MGs in islanding mode is proposed to maximize operational efficiency and minimize operational cost of the H-MG with full degree of freedom in automatically adapt the management problem under variations in the generation and storage resources in real-time as well, suitable for different size and types of generation resources and storage devices with plug-and-play structure, is presented. A self-adapting CEMS offers a control box capability of adapting and optimally operating with any H-MGs structure and integrated types of generation and storage technologies, using a two-way communication between each asset, being a unique inherent feature. This CEMS framework utilizes feature like day-ahead scheduling (DAS) integrated with real-time scheduling (RTS) units, and local energy market (LEM) structure based on Single Side Auction (SSA) to regulate the price of energy in real-time. The proposed system operates based on the data parameterization such as: the available power from renewable energy resources, the amount of non-responsive load demand, and the wholesale offers from generation units and time-wise scheduling for a range of integrated generation and demand units. Experimental validation shows the effectiveness of our proposed EMS with minimum cost margins and plugand-play capabilitities for a H-MG in real-time islanding mode that can be envisioned for hybrid multi-functional smart grid supply chain energy systems with a revolutionary architectures. The better performance of the proposed algorithm is shown in comparison with the mixed integer non-linear programming (MINLP) algorithm, and its effectiveness is experimentally validated over a microgrid test bed. The obtained results show convergence speed increase and the remarkable improvement of efficiency and accuracy under different condition.

“…A small power system consisting of power converter-based generation, ES devices, small classic synchronous generation, and various types of loads forms a microgrid (MG) [4]. While a number of research works on MG have been done on various aspects, including control strategy [5][6][7][8][9][10], energy management systems [11][12][13][14][15][16][17], marketing policies [18][19][20][21] and system design [22][23][24][25][26][27], this paper mainly focuses on the optimal sizing of Distributed Energy Resources (DERs), especially the capacity of ES devices in MG.…”

Since renewable energy resource is universally accepted as a promising method to solve the global energy problem, optimal planning and utilization of various distributed generators (DG) and energy storage (ES) devices deserve special concern. ES devices possess various characteristics in power density, energy density, response speed (switching speed) and lifetime. Besides, as different load types have various requirements on power supply reliability according to their importance, coordinated planning with consideration of reasonable matching between power source and load can efficiently improve power supply reliability and economic efficiency via a customized power supply and compensation strategy. This paper focuses on optimization of power source capacity in microgrid and a coordinated planning strategy is proposed with integrated consideration of characteristics of DG, ES and load. An index named additional compensation ratio (ACR) for balancing economic efficiency and reliability is proposed and considered in the strategy. The objective function which aims to minimize life cycle cost (LCC) is established considering economic efficiency, reliability and environmental conservation. The proposed planning strategy and optimizing model is calculated and verified through case study of an autonomy microgrid.
