摘要：
本文研究了分布式发电（DG）对输电网的影响以及美国不同州不同地理位置的定价策略。通常已知配电馈线上的DG会影响电压调节和电能质量。在某些情况下，DG可能提供电压和功率支持，但大多数情况会导致短期电压不稳定，这取决于多个变量，包括相对DG规模和位置、电力网络和负荷特性。因此，本文还探讨了以下问题：DG与传统发电站有何不同？不同DG对电网的渗透水平及其对IEEE相关标准的合规性如何？讨论了意外问题，特别强调电力保护协调问题，以及使用DG的潜在优缺点。尽管分布式发电（DG）允许从多个来源收集能源，并可能减少环境污染，但我们随后将讨论影响不同州DG单元电价的主要因素。
英文摘要：
In this paper, we investigate the impact of the Distributed generation (DG) on Power Transmission Grid and pricing strategy for different geographical locations in different states, generally distributed generation (DG) on distribution feeders is known to have an impact on voltage regulation and power quality. A DG might provide voltage and power support in some cases, but most cases cause short term instability voltage, depending on the several variables, including relative DG size and location, power network and load character, so This paper also addressing to the following questions: the different between DG and conventional power station? What are penetration levels of different DG to the power grid and compliances to the IEEE relevant standards, discusses unexpected issues with a special emphasis on power protection coordination problems, potential advantage and disadvantage to using DG while Distributed Generation (DG) allows collection of energy from many sources and may provide lower environmental pollution then we will discuss what would be the main Factors affecting Electricity Prices of DG units at different states.
