Increased green energy presence in distribution power networks can resolve rising energy demands while also reducing fossil fuel consumption, as well as providing economic and technical merits. However, the quantity of power delivered to customers cannot be allowed to take precedence over the quality of that electricity. This is because the high penetration of the renewable-based power generation comes at the cost of power quality (PQ) deterioration, especially at the point of common coupling (PCC), owing to nonlinear characteristics of renewable-based distributed generation (DG) systems and precontamination of modern distribution grids. So, the function of PQ improvement technologies unavoidably comes into the picture when the hosting capacity (HC) of renewable energy systems is constrained by any of the grid PQ performance indices. This paper investigates the application of a hybrid active power filter (HAPF) to improve the harmonic-constrained HC (HC-HC) of renewable DG systems in harmonically polluted distribution systems. A shunt type HAPF designing to achieve maximum HC-HC is considered as an optimization problem and solved by the firefly algorithm under several constraints the system particularly related to individual and total harmonic distortion limits in line current and voltage at PCC, harmonic currents overloading of distribution feeder. Aside from harmonics, constraints related to voltage rise and drop limits, as well as power factor, are also taken into account to ensure the optimal use of the HAPF as a compensator. The proposed HAPF-based HC-HC improvement approach's findings and efficacy are compared to those acquired from one of the literature's recently proposed techniques. Besides, the study is extended for HC-HC enhancement by HAPF, under changing the utility-side's background voltage distortion and the load-side's nonlinearity level conditions.The performed extended investigation of the system shows that HC-HC enhancing the effectiveness of the proposed approach is rather less susceptible to utility or customer side contribution to background distortion at the PCC.

“…To achieve this, DNO need to study the impacts of DG on their networks and subsequently determine possible measures for mitigating DG challenges to ensure a safe and reliable operation of distribution networks (Estorque & Pedrasa, 2016). Some of the mitigation measures include network reinforcements and upgrades, network reconfigurations, energy storage integration, and the installation of onload tap changers (OLTC) (Abad et al, 2017(Abad et al, , 2018Ahmadi et al, 2017;Ricciardi et al, 2019;Azibek et al, 2020;. These measures require high capital investment, hence they are less cost-effective (Abad et al, 2017(Abad et al, , 2018Ahmadi et al, 2017;Ricciardi et al, 2019;Azibek et al, 2020;).…”

“…An alternative and cost-effective solution is limiting DG penetrations to HCs of distribution networks (Abad et al, 2017), (Athari, Wang & Eylas, 2017). This is achieved through either active power curtailment or grid export limits (Ricciardi et al, 2019;Azibek et al, 2020).…”

“…There is no universal definition for HC, but the literature generally suggest that it is the maximum amount of DG that maintains a satisfactory operation of a distribution network (Estorque & Pedrasa, 2016;Athari, Wang & Eylas, 2017;Jain et al, 2019;Azibek et al, 2020). Like the impacts of DG, a distribution network's HC depends on numerous factors, including load profiles, generation profiles, the concentration of DG, network configuration, voltage levels, network characteristics, and climatic conditions, especially for weather-dependent DG such as solar PV and wind (Chiradeja, 2005;Fasina, Hassan & Cipcigan, 2015;Aziz & Ketjoy, 2017;Meddeb et al, 2018;Celvakumaran, Ramachandaramurthy & Ekanayake, 2019).…”

Distribution networks in Southern Africa and elsewhere are witnessing an unprecedented growth of consumer-side distributed generation (DG) courtesy of governmental interventions to maximise the utilisation of renewable energy resources through low-carbon grid-edge technologies. To deal with the increasing adoption of consumer-side DG, distribution network operators need to conduct technical studies to foster an understanding of the benefits and impacts of DG and the hosting capacity (HC) of existing distribution networks. This will aid the implementation of measures to manage grid exports. Using a distribution network in Namibia as a case study, this paper presents an algorithm for assessing the HC of consumer-side DG in existing distribution networks that are situated in areas anticipating high and uniform uptake of DG. The algorithm is a hybrid of deterministic and probabilistic methods. The uniqueness of the algorithm is the concept of calculating monthly HC. The algorithm was tested on a real existing residential distribution network and the results confirmed that HC varies monthly. However, the practical implementation of monthly HC requires upgrades to existing inverter technology, which currently contains a single export limit functionality. This opens the possibility to drive innovation in the inverter technology to develop a date-based multiple export limit functionality.
