…………………………………………………………………………………………………………………………..
We all know about power from renewable sources. It is no longer a new thing to be surprised. We have matured-enough technology available. We also know where to implement micro grid using renewable energy sources. Yes, rural area, far away from main grid, is the ideal location. When we talk about renewable energy, solar and wind power first come in our mind. Drawing energy from these sources, micro grid can potentially benefits humans if properly understood. Micro grid is indeed a revolutionary concept that has potential to minimize the dependence to main power grid, especially for the purpose of low to medium wattage consumption.
But how to fast utilize the solar or any other form of renewable energy is still not addressed. Let me raise some concerns that are the reasons why solar or other form of micro grid are still not prevalent. Today, carbon emission is a matter of concern. Absolutely true. But how many people actually know that? Or. How many people seriously think about that? Global temperature is rising; many cities can sink under sea-academicians know that. But common people, from developed and developing countries alike, really do not seriously bother about that. Why? Nobody of us actually can neither foresee future nor worry about what will happen 100 years later. We are biologically engineered not to wake up until the disaster happens. We cannot actually embody why micro grid is necessary.
We do have grand theories to save earth but little action thus far has been taken on the ground.

Therefore, to induce people into micro grid business,…...

Grid of the Future

...distributed generators is a common feature of all these frameworks. A series of challenges result from this evolution: the need to coordinate distributed participants, the need to harmonize standards and procedures, as well as the need to overcome a series of obstacles to change. This contribution reviews emerging network concepts and the associated challenges. Series compensation, reconfigurable power electronic systems and wide-scale use of phasor measurement units are early examples for these emerging solutions. Index terms – Power transmission, Power transmission planning II. CONCEPTS FOR FUTURE ELECTRICITY NETWORKS A. Microgrids In a system comprising distributed electricity generation, consumers and producers may be located within the same distribution system, reducing the need for long distance transmission. Therefore, the concept of microgrids, i.e. small distribution networks with energy sources and sinks of similar magnitudes has been proposed [1]. These network cells can be operated independently from their superordinated networks. This means that energy balancing, voltage and frequency control can be performed locally and that comparatively sophisticated protection and control systems for the (de-) islanding of these cells become necessary. B. Active distribution networks The concept of active distribution networks has been proposed based on the need to adapt the passive distribution infrastructure to the myriad of novel distributed participants expected to......

Operating Reserve Reliability Evaluation

...problem. The EENS of each optimisation period is analytically formulated as a piecewise linear function of system spinning reserve of that period. The parameters of the piecewise linear function are derived from the capacity outage probability table, which is established based on the exogenous unit schedule. The efficiency and validity of the proposed method is verified using the IEEE-RTS system. Spinning Reserve Estimation in Microgrids Wang, M.Q.;   Gooi, H.B.;   Sch. of Electr. & Electron. Eng., Nanyang Technol. Univ., Singapore, Singapore  This paper appears in: Power Systems, IEEE Transactions on Issue Date: Aug. 2011 Volume: 26 Issue:3 On page(s): 1164 - 1174 ISSN: 0885-8950 References Cited: 24 INSPEC Accession Number: 12175136 Digital Object Identifier: 10.1109/TPWRS.2010.2100414  Date of Publication: 28 一月 2011 Date of Current Version: 22 七月 2011 Sponsored by: IEEE Power & Energy Society  Abstract In this paper, a probabilistic methodology for estimating spinning reserve requirement in microgrids is proposed. The spinning reserve amount is determined by a tradeoff between reliability and economics. The unreliability of units and uncertainties caused by load and nondispatchable units are both considered. In order to reduce computation burden, various uncertainties are aggregated. A multistep method is proposed to efficiently consider the combinatorial characteristic of unit outage events. The computation efficiency......

Systems Enginnering

...also an important feature, without which the wind energy industry would no longer work," says Hennchen. Factors for Success: Consistency in Automation Technology Battery units are connected electrotechnically via a central control cabinet. A circuit breaker takes over with overload and short-circuit protection. The control electronics are supplied by a 24 V power supply. Visualisation is undertaken by open architecture software. "We can see great advantages in this consistent concept based on the model of Totally Integrated Automation (TIA)," Hennchen adds. For him, consistency and efficiently functioning complete systems are the key to sustainable success. Work on Hennchen's next project will be closer to home. He intends to develop a microgrid as part of a research project, which consists of 1.5 MW of installed wind energy, 2.5 MW of solar energy, and energy storage of 10 MWh. With this, many remote places on earth could be supplied with clean energy in a decentralised and stable way – for example in Tibet, where there is no central energy supply grid but many small grids fed by diesel generator sets. Hennchen sees a great future in the efficient storage of electrical energy, which he wants to actively shape: "With high-tech battery systems, wind energy amongst others can provide base load power efficiently and economically." http://www.renewableenergyworld.com/rea/news/article/2013/06/energy-storage-moves-wind-to-baseload...

Grid Energy Storage

...DOE’s 2011 Strategic Plan has identified a number of targeted outcomes in support of this goal, the most relevant to this mission includes reducing energy storage costs 30% by 2015 and supporting the integration of Plug-in Hybrid Electric and Battery Electric Vehicles as they shift load profiles8. Storage technology can help contribute to overall system reliability as large quantities of wind, solar, and other renewable energy sources continue to be added to the nation’s generation assets, furthering the goals of reducing greenhouse gas emissions and increasing energy security. Additionally, storage technology will be an instrumental tool in managing grid reliability and resiliency by regulating variable generation and improving microgrid and smart-grid functionality. For micro- and smart-grid technologies, storage can provide redundancy options in areas with limited transmission capacity, transmission disruptions, or volatile demand and supply profiles. The Department’s electric energy storage program can create economic opportunities, as well. A strong storage market will foster a robust manufacturing base of advanced electric energy storage devices in the U.S., and this capability can be leveraged for export opportunities in the robust foreign market for storage. Further, by enabling more efficient adoption of renewable energy sources in the US, storage can help promote US energy independence and reduce carbon emissions. Overview of this Report –This......

Future of Technology

...at Denmark, which gets around 20% of its power from scattered wind farms, for example. Sceptics argued that its reliance on micropower would cause more blackouts. It did not. At first glance, this shift toward micropower may seem like a return to electricity’s roots over a century ago. Thomas Edison’s original vision was to place many small power plants close to consumers. However, a complete return to that model would be folly, for it would rob both the grid and micropower plants of the chance to sell power when the other is in distress. Rather, the grid will be transformed into a digital network capable of handling complex, multi-directional flows of power. Micropower and megapower will then work together. abb foresees the emergence of “microgrids” made up of all sorts of distributed generators, including fuel cells (which combine hydrogen and oxygen to produce electricity cleanly), wind and solar power. The University of California at Irvine is developing one, as are some firms in Germany. “Virtual utilities” would then aggregate the micropower from various sources in real time – and sell it to the grid. Energy-storage devices will be increasingly important too. Electricity, almost uniquely among commodities, cannot be stored efficiently (except as water in hydroelectric dams). That means grid operators must match supply and demand at all times to prevent blackouts. But if energy could be widely stored on the grid in a distributed fashion, and released cheaply and efficiently......
