System Stability-Constrainted Optimal Protection Coordination in the Microgrid Including Renewable Energy Sources and Energy Storage

In this paper, the system stability-constrianted optimal protection coordination (SSCOPC) as stochastic problem in the microgrid with grid-connected and islanded operation modes, including renewable energy sources (RESs) and energy storage systems (ESSs), is presented. This problem to optimal regulation of the dual setting overcurrent relays (DSORs) and selecting the reactance size of fault cur...

New Protection Scheme for Internal Fault of Multi-Microgrid

Multi-microgrid has many new characteristics, such as bi-directional power flows, flexible operation modes and variable fault currents with different control strategy of inverter interfaced distributed generations (IIDGs). All these featuring aspects pose challenges to multi-microgrid protection. In this paper, current and voltage characteristics of different feeders are analyzed when fault occ...

A Novel Approach for Microgrid Protection Based upon Combined ANFIS and Hilbert Space-Based Power Setting

Abstract: Nowadays, the use of distributed generation (DG) has increased because of benefits such as increased reliability, reduced losses, improvement in the line capacity, and less environmental pollution. The protection of microgrids, which consist of generation sources, is one of the most crucial concerns of basic distribution operators. One of the key issues in this field is the protection...

The challenges of protection for Microgrid

Since the late 1970s, intensive efforts have been made to utilise renewable energy sources, such as wind, hydro, solar and tidal. However, the application of individual distributed generators can cause as many problems as it may solve. A better way to realise the emerging potential of distributed generation is to take a system approach that views generation and associated loads as a subsystem o...
