A Review of Operation Planning and Distribution Network Optimization of AADC Network

This paper presents the procedure used to optimize the 11kV network of AADC at Al Ain area in the United Arab Emirates. The paper first describes the details process used to forecast the summer peak load for all feeders and power transformers of all primary substations. Also, the optimization mathematical model is discussed as well as the actual preparation plans followed according to this model, where the 11kV network components are studied from different prospective concentrating on the security of supply standards (SoS) approved by the regulator in addition to the objective of load losses reduction. As a result of optimization study, the normally open points (NOPs) are chosen based on this criterion. Moreover, any expected load violations or security constrains like unsecured 11kV rings and 33/11kV substations are obtained and investigated for further operational and planning actions. Furthermore, contingency plans are prepared for the extreme unsecured cases to be ready and overcome any overloading problems that might be faced during the peak season or any emergency case. A standardized optimization process is driven illustrating different teams' contribution and efforts to achieve network optimization based on tasks responsibility.
