This paper presents a model for microgrid optimal scheduling considering multi-period islanding constraints. The objective of the problem is to minimize the microgrid total operation cost which comprises the generation cost of local resources and cost of energy purchase from the main grid. The microgrid optimal scheduling problem is decomposed into a gridconnected operation master problem and a...
This paper proposes a probabilistic model with the aim to reduce solar energy operation cost and CO2 emissions of multi-carrier microgrid. The MCMG in this study includes various elements such as combined heat power (CHP), electrical pump (EHP), absorption chiller, panels, thermal storages. A MILP is proposed manage commitment producers, storage equipment, amount selling/buying upstream network...
Enabling electricity markets is one of main characteristics of a smart grid that integrates advanced sensing technologies, control methodologies, and communication technologies into current power distribution systems. Intelligent Multi-Agent System (MAS) that provides platform for modeling autonomous decision making entities in de-centralized fashion can be used to implement market based power ...

variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. this paper proposes a decentralized method that restores the frequency of a microgr...
Microgrid concept acts as a solution to integrate large amounts of micro generation without disrupting the operation of utility grid. Power generation from renewable energy sources like wind, solar, fuel cells, microturbines etc will give significant momentum in near future. Thus, hybrid AC/DC microgrid will be the best solution to reduce multiple reverse conversions (dc-ac-dc or ac-dc-ac) in a...
The penetration of renewable energy in modern power system, microgrid has become a popular application worldwide. In this paper bidirectional converters for AC and DC hybrid microgrid application are proposed as an efficient interface. To reach the goal of bidirectional power conversion, both rectifier and inverter modes are analyzed. In order to achieve high performance operation and single-ph...
Modeling and Simulation of a Microgrid Testbed Using Photovoltaic and Battery Based Power Generation
Microgrid is a part of the power distribution system which uses renewable energy based of power generation connected to the grid system. Multi energy power generation is composed of renewable energy systems including photovoltaic, wind turbine, energy storage and local loads. Testbed of a microgrid system is the technique to ensure stable operation during faults and various network disturbances...
The present manuscript concentrates on the application of Fog computing to a Smart Grid Network that comprises of a Distribution Generation System known as a Microgrid. It addresses features and advantages of a smart grid. Two computational methods for on-demand processing based on shared information resources is discussed. Fog Computing acts as an additional layer of computational and/or commu...
The distribution loads, output of distributed generations (DGs) and dynamic power price present obvious time-sequence property, the typical property is studied in this paper. The model of microgrid (including adjustable load, DGs, storage and dynamic power price) is studied. A multi-timescale collaborative optimization model is built towards microgrid; main measures in different timescale optim...
