Transient Stability Analysis of Photovoltaic System with Experimental Shading Effects

Abstract

This paper presents the transient stability analysis of a photovoltaic (PV) system with account shading effects. Voltage and transient stability effect of PV system are assessed functions of an experimental study. The current advances in shading effect and temperature control of PV panels are studied. The study is performed on modeling and simulation of PV system with account shading effect. A shading effect system is introduced to reflect the transient response characteristics of PV generation model. An experimental setup is designed, constructed and assembled. The setup is provided with the necessary measuring instruments to carry out the required tests. A perspective on the other shading techniques for PV panels will be discussed in this paper.

Economical Benefits of Integrating Solar Energy Based DG units on an Existing Low Voltage Distribution Network in Pakistan

“…Many countries around the world have increased their solar photovoltaic generation capacity from kW to MW in recent past [15], [16]. In order to overwhelmed this electricity deficiency and generate electricity from renewable energy sources in Pakistan the best choice is the utilization of PV systems as it requires negligible running cost, harmless and do not contain any moving parts [17], [18]. A study on optimum size of a solar photovoltaic inverter for 3kW PV system is carried at QUEST Nawabshah Sindh Pakistan in [19] and is suggested to be integrated at low voltage distribution network.…”

Impact of large photovoltaic power penetration on the voltage regulation and dynamic performance of the Tunisian power system

“…In brief, larger PV power plants should remain connected with the power grid throughout large grid voltage disturbances because the disconnection of this large PV power may further deteriorate voltage recovery during the disturbance and after fault recovery (Kim et al., 2013). This phenomenon attracts the attention of many researchers towards the low-voltage ride-through (LVRT) competency of PV solar plants with higher levels of generation (Daniel et al., 2017; Moursi et al., 2013; Saïdi et al., 2018a). Since the LVRT capability of PV power generators supports the grid voltage recovery, the integration of PV power plants with a varied range of generation capacity, have been studied (Ruiz, 2011; Tamimi et al., 2011).…”

“…The influence of ambient conditions, i.e. temperature and solar radiation level, on the grid voltage, power, and frequency at the switching-in instance of large-scale PV power plant with the grid have been evaluated in (Ana and Oriol, 2016;Saı¨di et al, 2018aSaı¨di et al, , 2018b. Moreover, the techniques of integrating SPVGPs with large power generation with the power transmission and distribution networks have been presented in (Delille et al, 2012;Eftekharnejad et al, 2013;Khan Mohammed et al, 2013).…”

SFCL-SMES Control for Power System Transient Stability Enhancement Including SCIG-based Wind Generators

“…So, it is important to analyze the transient stability of power systems including wind power stations. In power system stability studies, the term transient stability usually refers to the ability of the synchronous machines to remain in synchronism during brief periods that follow large disturbances, such as severe lightning strikes, loss of heavily loaded transmission lines, loss of generation stations, or short circuits on buses [3][4]. On the other hand, the braking resistor (BR) has been recognized and used as a cost-effective measure for transient stability control of synchronous generators for a long time.…”
