【 摘 要 】

Integration of large-scale variablerenewable energy (VRE) generation resources -- wind andsolar -- into national grids has been gaining importance ascosts of these technologies, especially that of solar,continues to fall rapidly. However, there continues to be alack of a framework to systematically analyze the roleplayed by large-scale VRE integration for most developingcountries. This study develops such a framework and appliesit to analyze VRE policies in Bangladesh. The study uses aleast-cost planning approach to assess the volume of solarand wind that can technically and economically be integratedin the power system, accounting for spinning reservegeneration capacity requirements and adequacy oftransmission capacity. The study shows that solar and windcan provide a significant share of the 13 to 21 GW of newcapacity needed by 2025 to meet rapidly growing electricitydemand, although most of it does not pass the cost/benefittest in the near term till 2022. Efforts are also requiredto cope with what otherwise would be a large and costlyincrease in on-demand ("spinning") reservecapacity. The analysis demonstrates how an investmentstrategy to cover peak demand, and prudent changes in systemoperational practices, allow for the system to provide theneeded reserve capacity without a prohibitive increase insystem costs. In addition, the study examines the adequacyof transmission capacity for the first large-scale solar andwind project in Bangladesh.
