Microgrids can operate both in grid-connected and islanded modes. It is essential to protect microgrids against all types of faults in both of the operation modes. Conventional overcurrent protection schemes are not adequate for microgrids due to bidirectional flow of fault current and limited flow of fault current through semiconductor devices. In addition, the setting values of all the concer...
From the Internet of Energy point of view, adjacent building combined cooling, heating and power with microgrids (BCCHP microgrids) should be interconnected, which will generate better benefits, both economically and environmentally, from scarce energy resources through intelligent coordination. The interconnected-BCCHP (IBCCHP) microgrids will not only support energy with each other but also b...
This paper describes microgrids in the smart grid architecture, autonomous systems interacting through the Energy Services Interface as defined by the OASIS Energy Interoperation [1] specification. We define for the purposes of system architecture what a microgrid is. The several types of existing microgrids are defined, based on the motivations of those that operate them, the technologies they...
This paper presents an optimal coalition formation mechanism of microgrids in a smart distribution system and analyzes the characteristics from the coalitional game theoretical perspective. Microgrids coalitions can (1) minimize the energy burden and dependency on the utility grid, (2) minimize the overall grid network power loss, and (3) maximize intra-coalition energy transfer. In order to fo...
The growing interest in sharing the renewable-energy resources in power microgrids presents major challenge from the perspective of reliable operation and control of the power systems. The issue of the microgrids autonomous control has received a considerable attention in the last decade. As the architecture of the power system control, a hierarchical control scheme can be implemented for the i...
This paper proposes a multi-agent system for energy resource scheduling of an islanded power system with distributed resources, which consists of integrated microgrids and lumped loads. Distributed intelligent multiagent technology is applied to make the power system more reliable, efficient and capable of exploiting and integrating alternative sources of energy. The algorithm behind the propos...
This paper studies a secondary voltage control framework of the microgrids based on the consensus for a communication network of multiagent. The proposed control is designed by the communication network with one-way links. The communication network is modeled by a directed graph. At this time, the concept of sampling is considered as the communication constraint among each distributed generator...
Networked Microgrids (NMGs) offer a new, more resilient alternative to traditional individual Microgrids (MGs). Even though networking existing microgrids presents clear advantages, the scalable and resilient communication and control infrastructure necessary for supporting this innovation does not yet exist. This paper addresses this challenge by developing a Software-Defined Networking (SDN) ...
In this paper, Multi-Microgrids (MMG) are considered as future smart distribution grids, in which small scale energy resources (SSER) are main power generation units with small scales. Optimal operation of microgrids in defined intervals is carried out to achieve economic conditions in distribution systems. The defined operating problem is optimized using a heuristic algorithm considering uncer...
