Renewable energy sources are gradually being recognized as important options in supply side planning for microgrids. This paper focuses on the optimal design, planning, sizing and operation of a hybrid, renewable energy based microgrid with the goal of minimizing the lifecycle cost, while taking into account environmental emissions. Four different cases including a diesel-only, a fully renewabl...

Renewable Energy based microgrids are being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. The technical challenges associated with the operation and controls are immense. Electricity generation by Renewable Energy Sources is of stochastic nature such that there is a demand for regulation of voltage output in order to ...

Wind energy conversion systems are now occupying important space in the research of renewable energy sources with microgrid. The main challenge in wind power generation is power quality problem and their connection with the distribution network in microgrid. The main factor behind poor power quality is the impact of harmonics in current and voltage in power network. In microgrid the converter a...

This paper presents the development of a decision support system (DSS) for a low-voltage grid with renewable energy sources (photovoltaic panels and wind turbine) which aims at achieving energy balance in a pilot microgrid with less energy consumed from the network. The DSS is based on a procedural decision algorithm that is applied on a pilot microgrid, with energy produced from renewable ener...

Two of the most important technologies for future power systems to reduce greenhouse gas are electric vehicles (EVs) and renewable generation. When EVs become more common, the overall demand of electricity will significantly increase because EVs consume a large amount of electricity. Also, a daily load curve with EVs heavily depends on how much electricity EVs consume and when electricity is co...

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...

This paper introduces a communication system model with renewable power supply. As we assumed a battery-free microgrid system with conventional power as a backup power supply, we propose a method of power state and data transmission scheduling for delay-tolerant communication networks, which reduces conventional power consumption by operating adaptively to changes in renewable power. We found t...

This paper presents a grid-tied microgrid testbed for development and verification of automated energy storage management systems. Different assets in the microgrid including renewable generation, programmable load and a battery unit are introduced. Structure of the communication network to monitor and control the assets is also described in details. Based on the microgrid configuration, a cent...

Optimal design of an electrical microgrid and sizing of its components seeks to balance capital investment with expected operational cost while meeting performance requirements. Calculating operational cost requires scheduling each microgrid component over some time period (dispatching) for each design evaluated. Heuristic or rule-based dispatch strategies typically consider only single time in...

The intelligent energy management system is operated automatically to ON and OFF the generating sources as per the load demand. The renewable energy sources used in this energy management system are solar, wind, fuel cell and energy storage element battery as an input source. These renewable energy sources are integrated into the main dc bus through dc-ac converter. Microgrid is basically a gro...
