“…However, the paper [1][2][3][4] disproves that the PMU placement is to validate the observability of the network. The analysis of load flow for a hybrid microgrid is implemented [5] to improve the stability index, and then the sensitive node can identify in the microgrid. PMU has become more familiar with monitoring the distribution grids.…”

In the present day, there is an enormous demand in the supply of energy to all users. Since the voltage stability for the distribution system is not steady under any circumstances, therefore, to solve the problem of voltage instability the entire distribution system must simplified properly. Thus, some active support is provided for balancing the demand for electrical energy supply. Hence, the problem of voltage instability has been solved by considering phasor measuring units (PMUs) using antlion optimisation proposed in this study. The cost of PMU has been analysed along with other factors such as observability for effectively placing the PMUs with the identification of the weakest node. The problem is solved by using a non-linear model and the effectiveness of the proposed approach is tested using IEEE-15, IEEE-33, IEEE-69 Radial Distribution Systems and Croatia distribution grid. The result shows that the suggested algorithm is more effective in getting the optimal PMU placements considering multi-objective. Hence, the maiden state estimation values for distribution topologies are used.

“…In [95], a voltage stability analysis framework for a hybrid microgrid system was proposed. The VSI index used in this method is based on the basic definition of voltage stability, contains the active and reactive power information of all nodes in the radial distribution network system, and takes the maximum value from calculation of the nodes as the VSI.…”

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.

“…As traditional or central power generation have long transmission line to the load centre, which may not economical and suitable for village electrification due to high power demand and electric losses in transmission system. The distribution generation with renewable energy sources near to load centre is more economical solution for rural electrification [2] [3]. For designing and planning of distribution generation system the stability and reliability is main concern for electric system due to instability of load demand and instability in generation from renewable energy sources, which may cause the voltage and frequency stability problem in isolated hybrid microgrid.…”

The village electrification is the main concern for government of India. The isolated Hybrid Microgrid with renewable energy sources has been growing rapidly for village electrification and it is going to play vital role for 100% electrification in rural area by 2020. For planning and designing of isolated hybrid microgrid the power system stability is major parameter and its main concern due to instability in load demand as well as in generation from renewable energy sources. For renewable energy sources, the controlling of frequency and voltage deviation is a great challenge. This paper is carry out the stability analysis for PV-Biomass based isolated hybrid microgrid on different load and generation conditions and carry out the effect on frequency stability
