“…q ( s ) and g ~ ( s ) can combine together to form the controller structure, as shown in Figure 13 (Jeya Veronica and Senthil Kumar, 2017c). Even the feedback structure of internal model control (IMC) shown in Figure 13 can be used as a controller for MG sources (Jeya Veronica and Senthil Kumar, 2017b).…”

The electric power generation over the past decade has moved from conventional fossil fuel-fired thermal power plants to tiny-scale system generating power through distributed generation units. A group of such distributed generation units and loads are termed as microgrids. Microgrids can be located near the load centers to supply the load without any loss of power. Frequency regulation in a microgrid operating in autonomous mode is critical because of the intermittent nature of the renewable sources employed. To maintain the frequency regulation within a tolerance limit in a microgrid, proper control schemes have to be adopted in order to increase or decrease the real power generation. Hence, this article explores and presents a critical review of different types of control strategies employed for frequency regulation in microgrids.

The existing UFLS schemes suggested for conventional power systems need to be reassessed in the presence of renewable energy sources and storage systems equipped with grid-supporting convertors. A new Event-Based Under-Frequency Inertia Emulation (EB-UFIE) plan is proposed in this paper as a substitute of traditional UFLS program to protect the system against the risk of generation trip and subsequent blackout. Trajectory sensitivities are used as a popular technique to predict the future behavior of the system through a mixed integer programming optimization problem. The proposed scheme has been tested on the modified New England 39-bus system including renewables and storages.

“…The isolated Hybrid Microgrid has been growing rapidly for village electrification across the world as well as in India, due to several potential and economic advantages. As conventional power sources are increasing the environmental pollution and more transmission losses, the renewable energy sources are more suitable resource for village electrification as clean energy source [1]. The government of India introduce many schemes for village electrification under rural electrification program grid connectivity and OFF grid mode with renewable energy sources.…”

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
