operation point will be at the intersection of the power-voltage profile of theload and the PV array. If the operation point is at the maximum power point (MPP), maximumpower from the PV array will be achieved. However, since the MPP is irradiation dependent,installation of a power regulator and continuous MPP tracking control technique are essential. Figure 1: Electrical characteristics of a PV panel in different illumination. B. Energy Storage Systems Since renewable energy have intermittent characteristics, energy storage systems arenecessary for a high penetration of energy into a power system. Energy storages are also ofcritical importance in power systems to meet peak demands and to improve the reliability of thepower
the current. That means for each event that occurs, six waveformsare recorded. These waveforms will be referred to as the voltage and current profiles. B. Sampling Waveforms The process of sampling raw captured waveforms entails determining which data to feed into the machine learningalgorithm. The PowerVisa has a sample rate of 256 samples/cycle [8], or 15,360 Hz for a 60 Hz grid. As such,analyzing the transient events would likely produce unreliable results. Because of this, the transient portion of thewaveforms are ignored, and the steady-state waveforms from the pre-transient and post-transient portions of eachevent were the chosen as the input for the NILM algorithm. For consistency, each waveform sample represents twocycles of

) Total Yearly SavingsThe system price was constrained by the allowed budget as inputted by the user. This is shown inthe following equation: Price = [A ∙ (Cost PV )] + [B ∙ (Cost ST )] + [𝐶 ∙ (𝐶𝑜𝑠𝑡𝐶𝐻𝑃 )] ≤ Budget (27)In Eq. (27), A and B are the number of solar PV and solar thermal panels, respectively. Thevariable C represents a value of 0 or 1 which indicates whether not a CHP system is installed. Itsvalue is dependent on the spark spread calculation and whether not CHP is deemed costeffective. The CostPV and CostST refer to the installed cost of one panel for both solar PV andsolar thermal systems. The prices that were used for the basic calculation were based on installedsystems on the Milwaukee School of Engineering

, and two PV panels connected in parallel. To keep the center of gravity even, thePV panels are placed opposite from each other as shown in Figure 4a. Placing them side by sidewill not only make the charging station look less appealing, but it would also cause unbalanceload distribution on the overhang. The USB ports are installed opposite from each other, and thecharging station have two sets of USB ports. Each set has a total of four USB ports, giving thecharging station a total of eight USB ports. Figure 4.

parameters. When designing a BMS,design considerations must be made for cell balancing. Cell balancing is the process ofequalizing charge across all cells within a battery bank, either through dissipation as heat orthrough the transfer of energy from high power cells to low power cells. To better understand themechanics of cell balancing, the design team reviewed the research of B. Yildirim et al. found inreference [3]. This article covers three methods of cell equalization in battery energy storagesystems (BESS). Cell balancing is an integral component to maintaining SOH. While cells of thesame voltage may be used in a system, “manufacturing and thermal variations, differences ininternal impedances, and self-discharging rates” will cause variation
-A. The fluid from bothstacks is directed into the single channel of this manifold. This differs from the feedingmanifolds as it does not have a blank back.Students used two feeding manifolds, as seen in Figure 10-B, each consisting of three layers ofacrylic (similar to the collecting manifold). This first layer of the manifold (facing the fuel cell)is for feeding the cells the fuel and oxidant, it has sets of two holes that will connect directly tothe fuel cells with Teflon tubing. Then, behind this first layer will be the channels that willprovide the separated fuel and oxidant to the holes described in the first layer. The final layer(facing the case of the fuel cell) will simply be a solid piece of acrylic to enclose the channels inthe
