“…Current energy schemes are not intended to care for large-scale amalgamation of photovoltaic energy, and respond to grid codes (Mansouri, Lashab, Guerrero and Cherif, 2020). The bid of able and online control methods, is very important for improved coordination between the various parts of modern electrical systems (Mansouri et al, 2020;Chihota, 2019). In grid-connected mode, collaborative energy management is where microgrid participants can cooperate and use resources effectively (Oladejo, 2018).…”

The purpose of this article, with practical focus, is to analyse the potential of Renewable Energy (RE) as the catalyst for a sustainable energy distribution sector in South Africa (SA) and promote collaboration between the manufacturers, government, and all relevant stakeholders. The research design was a systematic literature review. It used a qualitative research method, through a questionnaire, to evaluate the knowledge and views of professionals from the energy distribution sector, managers or leaders in the energy sector, and energy sector experts. The sample size selected was between 350 and 400 participants. The literature reviewed noted that photovoltaic (PV) energy was one of the primary RE sources for sustainable energy generation. Furthermore, installing capacity and investment continued to grow throughout SA. Of note was the value-added through distributed RE systems in respect of electricity provision. The energy poverty in SA was high, and the impact of the Covid-19 pandemic further contributed to the challenges experienced. The general conclusions were that due to global warming and increased large-scale pollution, the use of RE for power generation had become evident. The article offered the potential opportunities of RE as the catalyst for the sustainable energy distribution sector in SA. Criteria was developed to include or exclude relevant scientific literature, by identifying subject relevance, type of technology, geographic scope, intervention scale, and data type.

“…The proposed control strategy is a model-based algorithm, and its efficiency depends on the model fidelity. This paper uses an empirically validated PV array model [8], where the author fitted the experimental data to the model. We assume using perfect sensors and a good estimation of model parameters.…”

“…Lately, such a standard was modified to accommodate a high penetration of distributed resources, including PV generators, to play an essential role in frequency and voltage control. Besides, grid operators modified grid code to harness ancillary services imposed on PV plant operators to respond to the sudden change in grid frequency [8]. Recently, many research efforts have been made to find practical solutions to tackle the incorporation of large-scale PV system problems.…”

A Novel Cooperative Control Strategy to Mitigate PV Power Fluctuation and Increase its Penetration

This paper proposes a novel optimization-based power sharing control strategy to moderate PV power intermittency and increase its penetration. Such a control strategy aims to minimize the total PV power sensitivity to the light change by re-distributing the demand power among available PV units such that the demanding power met with minimal variation. PV plant is coupled with the grid utility, and it should maintain a specific amount of power determined by the grid operator. However, due to the PV power sensitivity to the light, the delivered power at the coupling point fluctuates and leads to undesirable responses such as grid frequency excursion, stability problems, and unoptimized power generation. To address such issues, we formulate an optimization problem to reduce the total PV power sensitivity by selecting the optimal reference voltage for each PV panel. We define the power sensitivity as the rate of power change to light fluctuation to be the objective function of the proposed optimization problem, and the selected reference voltages for all PV panels are the decision variables. Compared to other conventional power-sharing techniques such as the same utilization level, droop control, and lookup table, MATLAB simulation results verify the contribution of the proposed algorithm's performance superiority in PV power sensitivity reduction, grid stability assurance, and power generation enhancement. Moreover, when there is insufficient PV power to meet the grid operator's demand, the proposed algorithm automatically sets the entire PV plant to work at its MPP without switching circuits.

“…In this experiment, the authors conducted tests by varying irradiance and wind speed levels without knowing the actual weather conditions. The authors in [22] also reviewed the effects of PV integration on both active and reactive powers. They have also discussed the curtailment of active power during over-voltages and reactive power management during low voltage conditions and suggested PV forecasting for voltage stability management.…”

The World Energy Council, in its 2019 World Energy Scenarios Report, advised policymakers to identify innovative opportunities for the integration of renewable energy resources into existing electrical power systems to achieve a fast and affordable solution. However, large-scale industries with cogeneration units are facing problems in handling the higher penetration levels of intermittent renewable energies. This paper addresses large-size photovoltaic power integration problems and their optimal operation. This work considers the case of a chemical industry having both cogeneration power and solar photovoltaics. Here, a modified firefly algorithm and a hybrid power resource optimization solver are proposed. The results of the proposed method are compared with other benchmark techniques, to confirm its advantages. The proposed techniques can be used in industries having cogeneration power plants with photovoltaics for better optimization and to meet the guidelines specified in IEEE 1547. The voltage ramp index is proposed to determine the voltage ramp up and down with intermittent solar irradiance. Additionally, a machine learning technique is used to predict the cogeneration plant efficiency at different loads and the solar irradiance under varying weather conditions. Finally, this paper proposes the effectiveness of the modified heuristic technique and certain guidelines, including solvers for industrial use.
