Community Microgrids: A Guide City Leaders Seeking Clean, Reliable and Locally Controlled Energy,

Community microgrids are central pillars of today’s local energy revolution. Being developed in municipalities large and small, they are a key feature of the new clean and efficient electrical infrastructure that is beginning to transform America’s energy grid into a less centralized and more democratized entity. Mayors and city leaders are … [Read more...]

Control and Design of Microgrids

Economic, technology and environmental incentives are changing the face of electricity generation and transmission. Centralized generating facilities are giving way to smaller, more distributed generation partially due to the loss of traditional economies of scale. Distributed generation encompasses a wide range of prime mover technologies, such as … [Read more...]

Microgrid Communications using SDN Tech

As power utilities strive to improve the reliability of electricity delivery and become eco-sustainable, microgrids are gaining in popularity. However, there are challenges in extending network to microgrid communications. In order to enhance microgrid communications, the technology SDN is being used as a new way to communicate with microgrids. … [Read more...]

Communication Infrastructures for Microgrids

With the recent technological advancements in communication infrastructures, mobile and cloud computing, smart devices, and power electronics, a renewed interest in power systems research has emerged. When these enabling technologies are jointly utilized to sense and actuate power generation, distribution, and demand, the resulting smart- grid has … [Read more...]

Technical Challenges of Microgrids

Microgrids are becoming increasingly attractive to consumers and as such in the future, a great number of them will be installed at consumer’s sites. In this situation, conventional distribution networks that accept distributed generation connections may face serious technical challenges when its control and protection functions become more … [Read more...]

Oracle Microgrid Approach

Oracle has defined microgrids as typically contained electrical areas embedded in neighborhood(s), high-rise buildings, retail shopping areas, or commercial parks. They are generally located inside a single electrical utility’s service territory,1 and they rely on the utility for many services. However, they also operate semi-independently to … [Read more...]

Hybrid Microgrid: Reducing Diesel

The world’s economies are electrifying at an impressive rate. Between 2000 and 2008, the world electricity produced per capita has increased by over 30% percent. Much of this electricity, particularly in developing economies, has traditionally come from generators burning diesel fuel. This trend is beginning to change, however, as electricity users … [Read more...]

Protection of the Microgrid Concept

This report examines the protection problems that must be dealt with to successfully operate a microgrid when the utility is experiencing abnormal conditions. There are two distinct sets of problems to solve. The first is how to determine when an islanded microgrid should be formed in the face of the array of abnormal conditions that the utility … [Read more...]

Micropower System Modeling

The HOMER Micropower Optimization Model is a computer model developed by the U.S. National Renewable Energy Laboratory (NREL) to assist in the design of micropower systems and to facilitate the comparison of power generation technologies across a wide range of applications. HOMER models a power system’s physical behavior and its life-cycle cost, … [Read more...]
