“…Economic benefits of integrating the use of DC DERs into distribution systems [5][6][7][8][9][10][11] Optimal siting and design of grid-connected PV systems [12][13][14][15][16][22][23][24][25][26] PV output research [17][18][19][20][21] Techno-economic feasibility of an AC/DC hybrid distribution network [27][28][29][30][31][32][33] Optimal control of DC-DC, and AC-DC converters supporting DC distribution [8,[34][35][36][37][38][39] DC distribution-Analysis and optimization [40][41][42][43][44][45][46][47] To the best of the authors' knowledge, there are no existing works that present a coordinated optimization tool for the control of voltage controllers in DC distributed networks incorporating solar PV systems, such that solar power is maximized, and substation power is minimized.…”

“…A multi-objective optimization model is proposed in [l] as a design and planning tool to improve voltage balancing and system efficiency of two-phase bipolar DC distribution networks, such as DC light-emitting diode (LED) lighting systems and residential DC networks. The work proposed by Jia et al recognizes that the DC distribution systems can support future smart grids by facilitating high penetration of renewables and DC loads [47]. Thus, the authors propose a new fault detection and location method to improve protection in PV DC distribution systems.…”

Impact of Pseudo-Random Modulation on Measured Conducted EMI

“…The DFT is defined as follows in (4). (4) where, x[n] is the sampled signal in time domain, X[k] is the discretized amplitude spectrum, n is the integer value starting at the measure 0 to N -1 in the time domain. Finally, k is the starting integer at the measure 0 to N -1 of the signal in frequency domain.…”

“…The FFT algorithm can be summarized using the Discrete Fourier Transform (DFT). The DFT is defined as follows in (4).…”

“…In microgrid topologies, DC distribution systems have the potential to support high penetrations of distributed renewable energy generation systems [4]. Thus, most of the power electronic converters used in microgrid topologies are DC/DC converters [5].…”
