Based on the characteristics of electric vehicles (EVs), this paper establishes the load models of EVs under the autonomous charging mode and the coordinated charging and discharging mode. Integrating the EVs into a microgrid system which includes wind turbines (WTs), photovoltaic arrays (PVs), diesel engines (DEs), fuel cells (FCs) and a storage battery (BS), this paper establishes multi-objec...

The security of energy systems has always been one the most important issues operation. multi-carrier multi-microgrid (MCMMG) is novel structures in power system. High penetration renewable resources and their uncertainty, ability to operate isolation mode, presence hubs MCMMG increase importance assessment this type This paper presents a decentralized risk-based security-constrained optimal fl...

one of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. the cars intensify greenhouse gas emission in civic centers. one approach to reduce the emission is replacing the cars by plug-in electric vehicles (pevs). in spite of reducing the emission, pevs have some adverse effect on electric distribution networks. technical challenges such as load and...

The increasing interest in integrating intermittent renewable energy sources into microgrids presents major challenges from the viewpoints of reliable operation and control. In this paper, the major issues and challenges in microgrid control are discussed, and a review of state-of-the-art control strategies and trends is presented; a general overview of the main control principles (e.g., droop ...

As an important part of s mart grid, microgrid(MG) is a new form of s mart grid in the future. Microgrid(MG) technology can effectively integrate the advantages of new energy and renewable energy generation and provide a novel way for large-scale applicat ions of new energy and renewable energy connecting to grid. This paper deals with the problem of economic operation of microsources in the mi...

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...

Microgrid is one practical infrastructure to integrate Distributed Generations (DGs) and local loads. Its optimal operating strategy has aroused great attention in recent years. This paper mainly focuses on the multi-objective optimization of DGs in microgrid by using self-adaptive genetic algorithm (GA) and fuzzy decision. Five objective functions are taken into account comprising voltage offs...

Regarding the advances in technology and anxieties around high and growing prices of fossil fuels, government incentives increase to produce cleaner and sustainable energy through distributed generations. This makes trends in the using microgrids which consist of electric demands and different distributed generations and energy storage systems. The optimum operation of microgrids with consideri...

Recently, there have been more needs of the integrated efficient and systematic microgrid energy management for increasing distributed energy resources (DER). The configuration of microgrid is generally so variant that it is difficult to be standardized. For the fast and complete integration of software applications over each microgrid, a flexible real-time database (RTDB) platform for microgri...
