Abstract

Rapid growth of distributed energy resources has prompted increasing interest in integrated Transmission (T) and Distribution (D) modeling. This paper presents the results of a distributed generation from solar photovoltaics (DGPV) impact assessment study that was performed using a synthetic T &D model. The primary objective of the study was to present a new approach for DGPV impact assessment, where along with detailed models of transmission and distribution networks, consumer loads were modeled using the physics of end-use equipment, and DGPV was geographically dispersed and connected to the secondary distribution networks. The study highlights (i) how a lack of DGPV forecasting can increase the Area Control Error (ACE) at the transmission level for high penetration levels; and (ii) how capturing transmission voltage changes using integrated T &D can change simulated distribution voltage profiles and voltage regulator operations between integrated T &D and distribution-only simulations.

用输配一体化模型研究分布式太阳能光伏发电对电力系统的影响

分布式能源的快速增长引起了人们对集成传输(T)和分配(D)模型的兴趣。本文介绍了使用综合技术与发展模型进行分布式太阳能光伏发电(DGPV)影响评估研究的结果。本研究的主要目的是提出一种DGPV影响评估的新方法，其中与输电和配电网络的详细模型一起，使用最终用途设备的物理特性对消费者负荷进行建模，并且DGPV在地理上分散并连接到二级配电网络。该研究强调了(i)对于高渗透水平，缺乏DGPV预测如何增加传输级别的区域控制误差(ACE);(ii)使用集成输配电捕获传输电压变化如何改变集成输配电和仅分布模拟之间的模拟配电电压曲线和稳压器操作。
