“…In [92], a P-V-and V-Q-based static voltage stability analysis simulation was developed with the IEEE 14-bus test feeder connected with the PV and wind power generator. It was shown that the system voltage profile reached the collapse point when the battery system's power capability was increased.…”

The ongoing development of renewable energy and microgrid technologies has gradually transformed the conventional energy infrastructure and upgraded it into a modernized system with more distributed generation and localized energy storage options. Compared with power grids utilizing synchronous generation, inverter-based networks cannot physically provide large amounts of inertia, which means that more advanced and extensive studies regarding stability considerations are required for such systems. Therefore, appropriate analytical methods are needed for the voltage stability analysis of renewable-dominated power systems, which incorporate a large number of inverters and distributed energy sources. This paper provides a comprehensive literature review of voltage stability analyses of power systems with high levels of renewable energy penetration. A series of generalized evaluation schemes and improvement methods relating to the voltage stability of power systems integrated with various distributed energy resources are discussed. The existing voltage stability analysis methods and corresponding simulation verification models for microgrids are also reviewed in a systematic manner. The traditional and improved voltage stability analysis methods are reviewed according to the microgrid operation mode, the types of distributed generators, and the microgrid configurations. Moreover, the voltage stability indices, which play a crucial role in voltage stability assessments, are critically evaluated in terms of the applicable conditions. The associated modeling and simulation techniques are also presented and discussed. This contribution presents guidelines for voltage stability analysis and instability mitigation methods for modern renewable-rich power systems.

“…From the graph, we can infer that the input voltage is most stable for INC followed by HC, CV, P&O, and lastly PID. The battery load has a voltage that is constantly increasing due to its charging which contributes to instability especially when bigger load is used according to Gumilar and others (2020) [8]. Thottuvelil and Verghese (2000) said that the consequences of voltage change is the massive changes in current which overheats and reduce the battery life, due to the float charging mechanism caused by tiny impedance in the battery, hence voltage regulation is mandatory to ensure the battery is in optimal performance [9].…”

Renewable energy is a topic that is frequently researched recently due to the negative environmental changes brought by using non-renewable energy sources such as fossil fuels. The application of the renewable energy is wide including being used to charge a battery using buck converter in general charging system. However, the problems faced by these solar charging systems is the inability to regulate and stabilize the output of the PV module, causing the loss of efficiency of PV module. A mechanism that is used to solve the problem is to develop the algorithm for maximum power point tracking in PV module. Thus, the project aims to improve the performance of battery charging system by using different MPPT algorithms and compared their performance with issues being analyzed, and helped to suggest the best algorithm to maximize the power supply and consumption effectively based on the MATLAB/Simulink results. The MPPT techniques used in the study consist of Constant Voltage (CV), Perturb and Observe (P&O), Incremental Conductance (INC) and also Hill Climbing (HC). The algorithms will be used on buck converter and compared with conventional solar battery chargers that uses PID controller for voltage regulation. The results are obtained from measurements of various parameters and they will be compared with the theoretical value with error calculation to determine the efficiency of the mechanism and also analyzed to determine the causes and effects of the simulation and for comparison. The results show that different algorithms can affect the performance of the system, such as changing transient times, power efficiency, shape of graph and so on. In conclusion, the best algorithm is Incremental Conductance due to its high-power efficiency and stable parameter output for battery charging system, in which further work done can be continued to include more weather data and constructing complex algorithm as well.
