本文的目的是评估使用微电网在提高电压、减少排放量和节省电力损耗方面的价值。本文分为两部分，第一部分评估了微源（如燃料电池、微型发电机、太阳能电池、风力发电机等分布式发电机）的电压改善和功率损耗节约。结果表明，使用μ源可使电压降降低约3%，同时发现使用μ源可将功率损耗降低到不使用μ源时的三分之一以上。靠近μ源位置的母线电压比远离μ源位置的母线电压下降小。第二部分计算主电网和微电网微源的CO2、SO2、NOx和颗粒物排放量。结果表明，μ源在电力系统特别是可再生能源（太阳能和风能）中的应用将有助于减少或消除排放问题，解决温室气体问题。最后通过计算证明了微电网可以解决传统电力系统所面临的大部分问题，并保持周围环境的清洁，微电网将是未来的电力系统。
The objective of this paper is to evaluate the value of enhancement in voltage, amount of emission reduction and amount of power losses saving with using micro grids. The paper is divided in two parts, the first part evaluates the voltage improvement and power losses saving with micro (μ) sources (distributed generators like fuel cell, micro tur-bine, solar cell, wind turbine etc.). The obtained results indicate that using μ sources reduce voltage drop by about 3%, Also, it is found that using μ sources can reduce the power losses to more than one third of its value without using μ sources. The voltage at the buses near the μ sources location will suffer from small drop than the buses far from μ sources locations. The second part calculates amount of CO2, SO2, NOx and particulate matters emissions from main grid and from μ sources which forms micro grid. The results indicates that more penetration of μ sources in the power systems especially the renewable sources (solar and wind) will help in reducing or removing emission problems and solve the green house gas problems. Finally this paper proved with calculations that the micro grid can solve most of the problems which facing the conventional power system and keep the surrounding environment clean from pollution and the micro grid will be the future power system.
