Summary In the modern world, only conventional energy resources cannot fulfil the growing energy demand. Electricity is a fundamental building block of a technological revolution. Today, most of the electricity demand is met by the burning of fossil fuels but at the cost of adverse environmental impact. In order to bridge the gap between electricity demand and supply, nonconventional and eco‐friendly means of energy generation are considered. Renewable energy systems (RESs) offer an adequate solution to mitigate the challenges originated due to greenhouse gasses (GHG). However, they have an unpredictable power generation with specific site requirements. Grid integration of RESs may lead to new challenges related to power quality, reliability, power system stability, harmonics, subsynchronous oscillations (SSOs), power quality, and reactive power compensation. The integration with energy storage systems (ESSs) can reduce these complexities that arise due to the intermittent nature of RESs. In this paper, a comprehensive review of renewable energy sources has been presented. Application of ESSs in RESs and their development phase has been discussed. Role of ESSs in increasing lifetime, efficiency, and energy density of power system having RESs has been reviewed. Moreover, different techniques to solve the critical issues like low efficiency, harmonics, and inertia reduction in photovoltaic (PV) systems have been presented. Unlike most of the available review papers, this article also investigates the impact of FACTS technology in RESs‐based power system using multitype flexible AC transmission system (FACTS) controllers. Three simulation models have been developed in MATLAB/Simulink. The results show that FACTS devices help to maintain the stability of RESs integrated power system. This review paper is believed to be of potential benefit for researchers from both the industry and academia to develop better understanding of challenges and solution techniques for REs‐based power systems and future research dimensions in this area.

“…Hence, only detailed analysis of mode 4(5) is presented, although all other modes were studied. Also only 2nd order modal interaction coefficients (h2 4,5 kl z 0 k z 0 l ) were examined in detail for both NF-35,000 and NF-9310 models.…”

“…Moreover, power electronic (PE) converters interfacing these new technologies to the grid also raise some concerns. For example, the PE converters could form a virtual capacitance, which could interact with the AC grid to trigger an unstable subsynchronous oscillation in a relatively weak system [4]. Each type of RE or EV creates challenges ranging from over-voltage, under-voltage, harmonics, stability issues, and many more.…”

Power System Nonlinear Modal Analysis Using Computationally Reduced Normal Form Method

Increasing nonlinearity in today’s grid challenges the conventional small-signal (modal) analysis (SSA) tools. For instance, the interactions among modes, which are not captured by SSA, may play significant roles in a stressed power system. Consequently, alternative nonlinear modal analysis tools, notably Normal Form (NF) and Modal Series (MS) methods are being explored. However, they are computation-intensive due to numerous polynomial coefficients required. This paper proposes a fast NF technique for power system modal interaction investigation, which uses characteristics of system modes to carefully select relevant terms to be considered in the analysis. The Coefficients related to these terms are selectively computed and the resulting approximate model is computationally reduced compared to the one in which all the coefficients are computed. This leads to a very rapid nonlinear modal analysis of the power systems. The reduced model is used to study interactions of modes in a two-area power system where the tested scenarios give same results as the full model, with about 70% reduction in computation time.

SO far various studies have been done on the application of FACTS devices in the energy system [29,30].

In general, transmission lines are under-utilized and uncontrolled [1,2]. The line impedance, the receiving and sending ends voltages, and phase angle between the voltages determine the transmitted electrical power over a line [3,4]. Various types of flexible ac transmission system (FACTS) devices are employed to control different parameters of the transmission system, such as line impedance, voltage magnitude and voltage phase angle [5,6]. They also both enhancing controllability and increasing power transfer capacity of electric power transmission networks. In general, FACTS controllers can be divided into four categories based on their connection in the network as shown in Fig. 1: series controllers, shunt controllers, combined series-series controllers and combined series-shunt controllers. Static synchronous compensator (STATCOM) [7,8] and static synchronous series compensator (SSSC) [9,10] are one-port controller and unified power flow controller (UPFC) [11,12] and interline power flow controller (IPFC) [13,14] are two-port controller.
