“…The widely applied technique in signal processing is the FFT due to its simplicity and efficacy of estimating a large number of harmonics up to the aliasing point, as well as the ability to work in offline and online analysis. Hence, most industrial and domestic measurement instruments such as power quality analyzers and smart meters depend on it [15], [16]. Furthermore, the power quality standards often recommend this technique for estimating the harmonics [13], [14]; therefore, this paper considers this technique as a standardized method that merits to be analyzed and compared with the proposed method for SMGs applications.…”

“…Several techniques have been suggested in the literature to estimate the harmonics/inter-harmonics such as artificial neural networks [13], wavelet packet decomposition [14], fast Fourier transform (FFT) [15], [16], adaptive estimation of the fundamental method [17], Recursive least squares technique [18], Kalman filter (KF) [19], synchronous reference frame (SRF) [20], PQ-theory [21], adaptive cascaded delayed signal cancelation technique [22], [23], real and complex coefficient filters [24], and demodulation of power line signal and subsequent filtering [25]. Nevertheless, none is affirmed to work accurately in inter-harmonic assessment under system frequency drifts, though each exhibited its benefits.…”

Modern maritime microgrid systems are witnessing a revolutionary advancement by integrating more renewable energy sources and energy storage systems. The integration of these sophisticated systems is achieved, however, through the power electronics converters that cause severe harmonic contamination. This problem becomes more serious when some of these harmonics that are non-integer multiples of the fundamental (inter-harmonics) exist concurrently with both system frequency drifts and large-power transients, which is a commune issue in maritime microgrid systems such as shipboard microgrids. Hence, the performance of the widely signal processing algorithms applied in the measurement and communication systems such as the smart meters and power quality analyzers tends to worsen. To address this problem this paper proposes an effective method based on the eigenvalue solution to estimate the harmonics and inter-harmonics of modern maritime microgrid systems effectively. This method, which is a system frequency independent technique can work effectively even under large frequency drifts with short window width. The proposed method is evaluated under MATLAB software, and then the experimental validation is carried out via analyzing the electrical power system current of a bulk carrier ship.

Nowadays, electricity companies have started applying smart grid in their systems rather than the conventional electrical grid (manual grid). Smart grid produces an efficient and effective energy management and control, reduces the cost of production, saves energy and it is more reliable compared to the conventional grid. As an advanced energy meter, smart meters can measure the power consumption as well as monitor and control electrical devices. Smart meters have been adopted in many countries since the 2000s as they provide economic, social and environmental benefits for multiple stakeholders. The design of smart meter can be customized depending on the customer and the utility company needs. There are different sensors and devices supported by dedicated communication infrastructure which can be utilized to implement smart meters. This paper presents a study of the challenges associated with smart meters, smart homes and smart grids as an effort to highlight opportunities for emerging research and industrial solutions. Conventional Grid Smart Grid Electromechanical meters Digital Meters One way communication Two-way communications Few sensors Multiple sensors Manual monitoring Automatic monitoring Limited control Unlimited control Few Customer choices Many customer choices Manually generate fees Automatically generate fees Centralized generation Distribution generation distributing data over the network to the utility company. Thus, the utility company has the ability to produce a billing for the customer, which has all information about the energy consumption and other information. Moreover, Table I shows that
