“…Its effect is dominant when the PV array is operated in the voltage source domain. The value of parallel resistance ( ) depends on the leakage current which is primarily dependent on the fabrication technique used [17]. Accommodating the additional current loss due to the series and parallel elements to the ideal PV cell equation, we get (2) and the model is as shown in the Figure 2. ]…”

The objective of this paper is to improve the voltage profile of the grid in pertinence to grid due to power injection from distributed solar photovoltaic (PV) arrays. Weak grids are modeled as worldwide adaptation of net metering, transactive energy systems, and the possibility of further deterioration of power quality with higher grid penetration. In this paper, a solar PV integrated weak distribution grid modelled as the PV arrays being frequently connected in rural areas, due to various reasons like cheap real estate and lack of accessibility. In this paper, three case studies of PV generation are simulated, i.e., scheduled solar PV generation less than load requirement, PV generation equal to load requirement, and PV generation more than load requirement, by considering the daily solar irradiation and load demand profiles of a residential area under study.

“…Due to the high PV deployment in LV networks, reverse power flows could be seen when PV generation exceeds the load demand [2][3][4]. Consequently, a voltage rise along the distribution feeder could be [5][6][7][8][9]. Therefore, it is vital to introduce measures to mitigate these impacts and support high integration of solar PV into the existing LV grids.…”

Solar photovoltaic (PV) power generation has shown a worldwide remarkable growth in recent years. In order to achieve the increasing energy demand, a large number of residential PV units are connected to the low voltage (LV) distribution networks. However, high integration of solar PV could cause negative impacts on distribution grids leading to violations of limits and standards. The voltage rise has been recognized as one of the major implications of increased PV integration, which could significantly restrict the capacity of the distribution network to support higher PV penetration levels. This study addresses the performance of the off-load tap changing transformer under high solar PV penetration and a detailed analysis has been carried out to examine the maximum allowable PV penetration at discrete tap positions of the transformer. The maximum PV penetration has been determined by ensuring that all nodal voltages adhere to grid voltage statutory limits. The simulation results demonstrate that the first two tap positions could be adopted to control the grid voltage under higher PV penetrations thus facilitating further PV influx into the existing network.

“…Supposedly, Pandanus Amaryllifolius P-MFC can generate electrical energy by utilizing the microorganism's metabolisms in the rhizosphere. Thru photosynthesis, the plant produces nutrients in an amount that needed for plant growth and extra nutrients that are unutilized will be released into the rhizosphere [8][9][10][11][12]. This is where microbe functions as an oxidizing agent, reducing the organic substrate that is released.…”

Plant microbial fuel cell (P-MFC) is an electrochemical reactor that converts organic compounds to electrical energy through the catalytic reaction from electrochemically active bacteria (EAB). However, there is no sign of an attempt in developing the functional model in predicting the energy conversion and utilization of P-MFC. In this study, an analytic model is proposed to show the whole production process of the organic compound to electrical energy generation. Pandanus Amaryllifolius plant was used as sources of photosynthate, where biomass product from rhizodeposition, acetate was produced, and soil bacteria as the microbial culture, and air as the input to the cathode chamber. The proposed analytical model is able to predict the output of the P-MFC using the parameters from the experiment. The generated data from the model was then compared with the monitored data from the Pandanus Amaryllifolius P-MFC. The results show the electrical power output has a high similarity pattern with the bacterial growth curve model and able to achieve the coulombic efficiency of 95.32%.
