For the study of distributed generation and its impact on power system, this paper briefly introduces the basic concept, the advantages of distributed generation, and the concept and basic structure of micro-grid. From the power system planning, system voltage, power quality, island effect, relay protection and other aspects, this paper analysis and discusses the influence of distributed power on power system. To properly resolve the grid-connected distributed generation power influence, it will be helpful for the development of future of distributed power generation.

Distributed generation refers to a variety of technologies that generate electricity at or near where it will be used, such as solar panels and combined heat and power. Distributed generation may serve a single structure, such as a home or business, or it may be part of a microgrid a smaller grid that is also tied into the larger electricity delivery system , such as at a major industrial facility, a military base, or a large college campus.

How Microgrids Can Seamlessly Combine Distributed Energy Resources

Microgrids are a growing segment of the energy industry, representing a paradigm shift from remote central station power plants toward more localized, distributed generation—especially in cities, communities and campuses. The power to isolate from the larger grid makes microgrids resilient, and the ability to conduct flexible, parallel operations permits delivery of services that make the grid more competitive. Microgrids provide efficient, low-cost, clean energy, enhance local resiliency, and improve the operation and stability of the regional electric grid. They provide dynamic responsiveness unprecedented for an energy resource. Despite their many advantages, microgrids face significant barriers to widespread implementation. As a fundamental complication, microgrids face often-conflicting regulation at the federal, state and sometime local levels. As the Federal Energy Regulatory Commission FERC has recognized, even though they are generally located behind the meter on the distribution system, microgrids provide services that substitute for and compete with the services of wholesale generation.

A microgrid [1] is a decentralized group of electricity sources and loads that normally operates connected to and synchronous with the traditional wide area synchronous grid macrogrid , but can also disconnect to "island mode" and function autonomously as physical or economic conditions dictate. In this case the microgrid is also called an autonomous, stand-alone or isolated microgrid. In this way, microgrids improve the security of supply within the microgrid cell, and can supply emergency power, changing between island and connected modes. As a controllable entity, a microgrid can effectively integrate various sources of distributed generation DG , especially renewable energy sources RES. Control and protection are difficulties to microgrids, as all ancillary services for system stabilization must be generated within the microgrid and low short-circuit levels can be challenging for selective operation of the protection systems. The United States Department of Energy Microgrid Exchange Group [8] defines a microgrid as a group of interconnected loads and distributed energy resources DERs within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid.

This chapter examines the current energy scenario for microgrids over the world and discusses the challenges and opportunities due to the increasing penetration of distributed power generation systems and electric vehicles EVs into the microgrids. Wind power and solar power can be generated by wind turbines and photovoltaics, respectively, while these are intermittent in nature. EVs and hybrid EVs use a battery energy storage system and charging facilities while the latter also include an Internal Combustion Engine ICE to provide an extra energy source. The features of these systems in the context of microgrids are studied in detail, in terms of their components, efficiency, reliability, charging and discharging arrangements, active and reactive power control. The chapter provides a reference to the development of microgrid systems especially for developing countries. Development and Integration of Microgrids.

The future electricity network must be flexible, accessible, reliable, and economic according to the worldwide smartgrid initiative. The application of individual distributed energy resources as microgeneration can cause problems such as local voltage rise, the potential to exceed thermal limits of certain lines and transformers, islanding and have high capital cost [ 3 ]. Microgrid can be a better solution for these problems. The choice of a distributed generator mainly depends on the climate and topology of the region. These topics are beyond the scope of this review. A short description of the advantages and disadvantages of the widely available and feasible distributed generators DGs is provided.


The microgrid concept enables high penetration of DG without requiring re-​design or re-engineering of the distribution system itself. II. EMERGING GENERATION.

Future of Microgrids with Distributed Generation and Electric Vehicles

Сьюзан осталась стоять. - Коммандер, если вы все еще горите желанием узнать алгоритм Танкадо, то можете заняться этим без. Я хочу уйти.

Сьюзан не любила бывать в шифровалке в неурочные часы, поскольку в таких случаях неизменно чувствовала себя запертой в клетке с гигантским зверем из научно-фантастического романа. Она ускорила шаги, чтобы побыстрее оказаться в кабинете шефа. К рабочему кабинету Стратмора, именуемому аквариумом из-за стеклянных стен, вела узкая лестница, поднимавшаяся по задней стене шифровалки. Взбираясь по решетчатым ступенькам, Сьюзан смотрела на массивную дубовую дверь кабинета, украшенную эмблемой АНБ, на которой был изображен могучий орел, терзающий когтями старинную отмычку. За этой дверью находился один из самых великих людей, которых ей довелось знать.
