Microgrid (MG) with different technologies in distributed generations (DG) and different control facilities require proper management and scheduling strategies. In these strategies, in order to reach the optimal management, the stochastic nature of some decision variables should be considered. Therefore, we proposes a new stochastic-based method for optimal daily energy management (SDEM) of MGs...

The power-sharing possibility amongst microgrids (MGs) in networked (NMGs) offers multiple profits to the NMG by employing an applicable energy management system. An efficient system can provide adequate compromise terms of component sizing NMGs through MG collaboration. This paper proposes a procedure size for isolated hybrid microgrid. proposed design relies on optimum operation individual MG...

In this paper, a grid connected microgrid with multiple inverter-based distributed generators (DGs) is considered. DG in FFC mode regulates the microgrid as a controllable load from the utility point of view as long as its output is within the capacity limit. The transition mode causes a change in frequency of microgrid due to the loss of power transferred between main grid and microgrid. Frequ...

A microgrid is a cluster of interconnected distributed generators, loads and intermediate storage units that cooperate with each other to be collectively treated by the grid as a controllable load or generator. Power quality events and pre-set conditions will make the microgrid disconnect from the main grid and operate as a separate island. This paper enumerates and discusses the issues concern...

Nuclear energy is being reconsidered worldwide as a low-carbon and dispatchable source. Following the development of Small Modular Reactors (SMR) to reduce capital costs increase safety new nuclear power plants, microreactors are designed by several companies. Microreactors usually defined SMR with output in range 1–20 MWe. They can operate part electric grid, independently from grid or microgr...

When a microgrid is mainly supplied by renewable energy sources (RESs), the frequency deviations may deteriorate significantly the power quality delivered to the loads. This paper proposes a frequency-based control strategy, ensuring the frequency among the strict limits imposed by the Standard EN 50160. The frequency of the microgrid common AC bus is determined by the energy storage converter,...

In recent years, DC microgrid has attracted considerable attention of the research community because of the wide usage of DC power-based appliances. However, the acceptance of DC microgrid by power utilities is still limited due to the issues associated with the development of a reliable protection scheme. The high magnitude of DC fault current, its rapid rate of rising and absence of zero cros...

A microgrid can be operated in on-grid or off-grid, mode using distributed energy resources (DER), among which combined heat power can play an important role in increasing the total energy efficiency. This paper reports the total solutions to the problem of scheduling DER including CHP and their dispatch, called a generation application package. To increase the accuracy of forecasting, this pap...

As usual, the microgrid operates in grid-connect mode, but, when a fault occurs in the upstream grid, it should disconnect and shift into islanded operation mode. In grid-connect mode, the controlling power at the PCC is necessary management function rather than the frequency and voltage. However, the controlling the frequency and voltage is asked in islanded mode. To achieve these management g...
