The explicit model of the energy yield with respect to irradiance and cell temperature of a photovoltaic (PV) system can be apprehended using pvsyst software. Building on this data, this paper addresses performance challenges for JA Solar, JAP6 (DG) 60-235 solar PV module driving a load of Enphase, IQ6-60-x-240 grid inverter. The data modeling reflects correlation of 62% between panel temperature and output efficiency. Researchers in the past have claimed that extreme temperature exposure as one of the main impediment in decline of solar panel's life span and figured 25 °C as the ideal temperature for optimum yield. This research proposes the Internet of things (IoT)-based smart solar energy system (SES) for smart cities that automatically tune the low-powered cooling unit to lower panel's temperature to outmatch energy yield and augment solar panels life. The analog design of the cooling mechanism is set up for temperature range from −10 °C to 85 °C using hybrid op-amp proportional–integral–derivative (PID) controller and heat sink/fan with surface mount temperature sensor to maintain module temperature. The experiment analysis showed improvement of 1.7% to 2.99% in output efficiency after considering 1.8 W total power intake of the cooling circuit relative to the pvsyst v6.74 results. To access temperature data of solar panel and output current along with in-built system's current consumption, IoT accreditation is done using node MCU and Wi-Fi module.

The main objective of this paper the solar energy system will be equipped with two type of converters DC/DC and DC/AC. The DC/DC boost converter is generally driven by the MPPT technique. We need to design a single controller for both the converters that would meet the power requirements and enhance its efficiency. To enhance the active power output by utilizing the designed controller for both the converters. The power enhancement would be done by utilizing a hybrid integrated constrained particle swarm optimization technique that is also modified to meet the MPPT requirements of the solar energy system. the result of The single controller has resulted in the following key improvements. The algorithm was first incorporated with the MPPT algorithm for the boost converter which has improved the DC voltage profile from 500 V to 595 V. The active power output from the system has enhanced to 113KW from 100Kw which is also stable as compared to the system having dual controllers for the converters. The PSO algorithm is so constrained in a manner such that the output voltage and current distortion has also reduced. The voltage output distortion level from the hybrid constrained PSO controllers was found to be 0.20% which is less than 0.26% of the system having dual controllers Also the THD level in the current output from the hybrid PSO integrated algorithm was reduced to 0.16% from 3.36% in the solar PV system modeled with dual controllers.

A reconfiguration technique using a switched-capacitor (SC)-based voltage equalizer differential power processing (DPP) concept is proposed in this paper for photovoltaic (PV) systems at a cell/subpanel/panel-level. The proposed active diffusion charge redistribution (ADCR) architecture increases the energy yield during mismatch and adds a voltage boosting capability to the PV system under no mismatch by connected the available PV cells/panels in series. The technique performs a reconfiguration by measuring the PV cell/panel voltages and their irradiances. The power balancing is achieved by charge redistribution through SC under mismatch conditions, e.g., partial shading. Moreover, PV cells/panels remain in series under no mismatch. Overall, this paper analyzes, simulates, and evaluates the effectiveness of the proposed DPP architecture through a simulation-based model prepared in PSIM. Additionally, the effectiveness is also demonstrated by comparing it with existing conventional DPP and traditional bypass diode architecture.

Decoupled Control

A reliable grid connected Photovoltaic (PV) system require effective control schemes for efficient use of solar energy. This paper presents a three-phase grid tied PV system with decoupled real and reactive power control to achieve desired power factor with Maximum Power Point Tracking (MPPT) controller to get maximum solar energy. The synchronous reference frame (dq) control along with decoupling concept is used to control the DC-AC inverter output, while the Phase Locked Loop (PLL) synchronization technique is used to monitor and synchronize the voltage and current at the grid side. The DC-DC converter with Incremental Conductance (InC) based MPPT model is also designed in this paper due to better accuracy compared to Perturb & Observe (P&O) algorithm. The simulation is performed in MATLAB/SIMULINK and a 31.5 kW PV system is modelled to get 30 kW power with the help of MPPT at Standard Test Conditions (STC). Any power factor value between 0.85 lagging to 0.9 leading can be obtained by changingreference q current in this inverter control strategy. The simulation results show that the change of reactive powerdoes not affecttheactive power values of the system, which verifies the effectiveness of the decoupled control strategy of the inverter.

Net Energy Metering

Malaysia has moved forward by promoting the use of renewable energy such as solar PV to the public to reduce dependency on fossil fuel-based energy resources. Due to the concern on high electricity bill, Universiti Malaysia Perlis (UniMAP) is keen to install solar PV system as an initiative for energy saving program to its buildings. The objective of this paper is to technically and economically evaluate the different sizing of solar PV system for university buildings under the Net Energy Metering (NEM) scheme. The study involves gathering of solar energy resource information, daily load profile of the buildings, sizing PV array together with grid-connected inverters and the simulation of the designed system using PVsyst software. Based on the results obtained, the amount of solar energy generated and used by the load per year is between 5.10% and 20.20% from the total annual load demand. Almost all solar energy generated from the system will be self-consumed by the loads. In terms of profit gained, the university could reduce its electricity bill approximately between a quarter to one million ringgit per annum depending on the sizing capacity. Beneficially, the university could contribute to the environmental conservation by avoiding up to 2,000 tons of CO2 emission per year.

The penetration level of a PV system is often limited due to the violation of voltage variation introduced by the large intermittent power generation. This paper discusses the use of an active power curtailment strategy to reduce PV power injection during peak solar irradiation to prevent voltage violation so that the PV penetration level of a distribution feeder can be increased to fully utilize solar energy. When using the proposed voltage control scheme for limiting PV power injection into the study distribution feeder during high solar irradiation periods, the total power generation and total energy delivered by the PV system over a 1-year period are determined according to the annual duration of solar irradiation. With the proposed voltage control to perform the partial generation rejection of PV systems, the optimal installation capacity of PV systems can be determined by maximizing the net present value of the system so that better cost effectiveness of the PV project and better utilization of solar energy can be obtained.

Like all modes of transportation that use fossil fuels, ships produce carbon dioxide emissions that significantly contribute to global climate change and ocean acidification. Additionally, ships release other pollutants that also contribute to the problem and exacerbate climate change. Considering the large volume of ships on the high seas, ship emissions pose a significant threat to human health. The ocean is exposed to vast amounts of sunrays and has a great potential to be explored by the maritime sector and green power industry. Solar energy hybrid assisted power to support auxiliary power for the instruments on board the vessel is explored in a UMT vessel. The vessel that is used in this case study is Discovery XI, which is a 16.50 meter diving boat owned by University Malaysia Terengganu. The study explores the feasibility of using solar energy as a supporting power for marine vessel auxiliaries. The reduction of fuel usage after installing the solar PV system on the boat is determined, as well as an economic analysis. The power requirement for the vessel’s electrical system is estimated. The fuel and money saved is also estimated for comparison purposes of the vessel using the solar PV system and the vessel without the PV system. Economic analyses are performed, the Annual Average Cost (AAC) between a vessel using solar PV system and a vessel without solar PV system is estimated, and the period of the return of investment for the vessel with solar PV system is also estimated. The use of a photovoltaic solar system to assist the boat power requirement will benefit the environment through Green House Gas (GHG) reduction, and the use of solar as a supporting alternative energy could cut the cost of boat operation through fuel savings.

There are approximately 200,000 households living in detached houses and gers (yurts) with small coal stoves that burn raw coal in Ulaanbaatar city. A proper heating system and improvement of the energy efficiency of residential dwellings are vitally important for Ulaanbaatar city to reduce air pollution as well as for the operation of the current central energy system. This study shows the experimental results for two gers with two different heating systems and different thermal insulation, for investigating the merits of each. The technical feasibility of the system consisting of an electric thermal storage (ETS) heater with a daytime charging schedule and areal photovoltaic (PV) system was also examined by using a simulation with software developed in MATLAB (R2020a, MathWorks, USA). As a result of the experiment, the indoor comfort level and energy efficiency of the ger with added insulation and an ETS heater with nighttime charging were shown to be enhanced compared with those of the reference ger. The ger with added insulation and the ETS heater consumed 3169 kWh for electric appliances and 5989 kWh for the heating season. The simulation showed that the PV self-consumption rate is 76% for the Ger 2 with the ETS heater because of the daytime charging schedule of the ETS heater. The PV system supplied 31% of the total energy consumed, with the remaining 69% from the main grid.

With the increasing global concerns about greenhouse gas emissions caused by the extensive use of fossil fuels, many countries are investing in the deployment of clean energy sources. The utilization of abundant solar energy is one of the fastest growing deployed renewable sources due its technological maturity and economic competitivity. In addition to report from the National Renewable Energy Laboratory (NREL), many studies have suggested that the maturity of solar energy systems will continue to develop, which will increase their economic viability. The focus of analysis in this paper is countries with hot desert climates since they are the best candidates for solar energy systems. The capital of Saudi Arabia, Riyadh is used as the case study due to the country’s ambitious goals in this field. The main purpose of this study is to comprehensively analyze the stochastic behavior and probabilistic distribution of solar irradiance in order to accurately estimate the expected power output of solar systems. A solar Photovoltaic (PV) module is used for the analysis due to its practicality and widespread use in utility-scale projects. In addition to the use of a break-even analysis to estimate the economic viability of solar PV systems in hot desert climates, this paper estimates the indifference point at which the economic feasibility of solar PV systems is justified, compared with the fossil-based systems. The numerical results show that the break-even point of installing one KW generation capacity of a solar PV system is estimated to pay off after producing 16,827 KWh, compared to 15,422 KWh for the case of fossil-based systems. However, the increased cost of initial investment in solar PV systems deployment starts to be economically justified after producing 41,437 KWh.
