“…Based on other research works, high level of DG penetration is likely to give a negative impact to the grid; change of voltage profile along the distribution network, increase in short circuit level, voltage transients due to connection and disconnection of DG, distruption in power quality and reliability of the system including overloading of lines and equipment that leads to thermal overloading. The severity of these issues depends on the penetration level of solar PV, the load characteristics, distribution system configuration and the location of solar PV in distribution system as shown in previous researchs [6][7], [11], [13][14]. Results obtained from previous research have shown that 25% DG penetration improves the transient stability of the grid, while the connection and high penetration of DG causes disturbance such as increase in fault level and affect power system protection performance [4], [11], [23].…”

“…Therefore, power system fault level should be monitored in order to maintain the reliability of protection equipment and availability of power supply to the customers. Two main factors that influence the impact of DG to power system reliability: first, the characteristic of distribution networks such as line impedance and system load [6] and second the DG itself such as type, location and size of DG that is to be connected to power system network [6][7], [11], [13][14].…”

Distributed Generation is generation of electricity from renewable energy resources, located closer to the customers or loads. Installation of Distributed Generation could improve voltage and power quality, mitigate voltage sags, minimize transmission system congestion, and provide more affordable capacity for utilizing renewable energy resources. However, high penetration of Distributed Generation to the existing national grid system may contribute several impacts including fault level, as well as the performance of power system protection. Monitoring of fault level is important in power system protection in order to sustain the health of power system networks. This paper investigates the impact of installing Distributed Generation to power system fault level. Three-phase symmetrical fault is simulated and analyzed for various sizes of distributed generation in IEEE 30 bus system using Power System Simulation for Engineering (PSS/E) software.<p class="MsoNormal" style="text-align: justify; text-indent: .5in;"><em><span style="font-size: 9.0pt; font-family: 'Arial','sans-serif'; color: black;">Distributed Generation is generation of electricity from renewable energy resources, located closer to the customers or loads.

“…Many studies have been conducted on PV with different problem approaches. Some researches demonstrated the benefit and detriment of PV penetration into the grid [3] when faults occur. In [4], the papers focus on optimizing power flow in the grid, finding optimal PV connection locations, or control solutions to improve operating efficiency, but the PV power level is assumed to be quite low in the grid or only care about the steady state of the grid.…”

Using renewable energy sources (RES) to face energy shortages in the context of rising load demand is a central issue in national power system planning. With low investment rates, rapid return on capital as well as many incentives from the government, solar energy is being more invested than other types of RES, as it can be seen as a rooftop and large-scale Photovoltaic (LSPV) system. However, if the LSPV penetrates too much into the grid, it will weaken the stability of the system, especially when a fault occurs. This paper aims to evaluate the transient stability of an actual distribution grid (DG) under different penetration levels of LSPV by ETAP software. The frequency and voltage responses will be presented in the results along with the rotor angle variation of a conventional generator located near the LSPV.

“…Therefore, the necessity of system inertial response is demanding. Based on system inertial response capability, many research efforts have been put to investigate the impact of DG penetration and their limits on the existing system following different dynamic and transient phenomena [4][5][6]. In near future, the wind farm may be required to participate in certain level of frequency regulation with major DG penetration level.…”

Renewable energy sources (RES) based distributed generation (DG) system results reduction of overall system inertia, which is likely to generate higher oscillations in the system during disturbance conditions. Therefore, DG penetration level has a significant impact on system stability and reliability. This study provides an in-depth analysis of Battery Energy Storage System (BESS) impact in providing primary frequency control to support increased wind penetration level. The BESS is modeled as a storage system with DC/AC converter and other associated power electronics interfaces. The objective is to replace the existing synchronous generator in proportion with the increasing penetration level of wind units while maintaining power system stability and reliability. The BESS model is developed in DigSILENT/PowerFactory and the system performances are simulated and compared with and without the BESS considering different disturbances such as single-phase-to-ground fault, and temporary line outage and load demand increment with various DG penetration level. It is shown through simulation results that BESS exhibits the ability to reduce system oscillations following disturbances and supports the increment of DG penetration level in the existing power system. Therefore, BESS can be seen the most viable measure of stability enhancement with renewable oriented sustainable future electric grid.
