Power System Reliability and Efficiency Improvement Project

The development objective of the Power System Reliability and Efficiency Improvement Project for Bangladesh is to improve the reliability and efficiency of the power system in Bangladesh through optimization of dispatch operation. The project comprises of three components. The first component, technical assistance consists of two sub-components: (i) primary frequency control trials and training for Power Grid Company of Bangladesh (PGCB) and National Load Dispatch Centre (NLDC) engineers and operators on modern, state‐of‐the‐art frequency control, and dispatch protocols; and (ii) capacity building and institutional review to: (i) acquaint NLDC staff with modern control theory, practical aspects of regulating frequency in real‐time through governor response as well as secondary control, and (ii) build power system dynamic modeling capability using power system simulation for engineers (PSSE). The second component, operational enhancements consists of three sub-components: (i) integration of generators to the NLDC’s supervisory control and data acquisition (SCADA) and energy management system (EMS) system; (ii) upgrading and modernization of the NLDC SCADA and EMS software; and (iii) optimization software for dispatch. The third component, removal of transmission bottlenecks and improvement of voltage quality consists of two sub-components: (i) the upgrade (by re‐conducting with higher capacity conductors) of selected congested 132 kV and 230 kV lines to address existing bottlenecks and enhance system transfer capability; and (ii) dynamic line rating (DLR)12 to improve utilization of limited transmission capacity on 400 km of six critical transmission lines identified by PGCB.
