Abstract

To fulfill electrical energy needs and ensure the sustainability of development in some area, generation expansion planning (GEP) is required. GEP optimizes the number, type, time and capacity of the generating units during a specified time horizon for fulfilling the demand. The optimization procedure is to minimize total cost under some technical constraints. In this paper, Long Term GEP in Sulawesi electricity system is determined considering the intermittent of renewable energy. Considering intermittent renewable energy in GEP, renewable energy proportion can increase by 9.77% to 19.32% and reduce coal energy from 75.19% to 61.67% in 2050. Another aspect is the environmental benefit of the system which the annual emission reduces from 45.8 million tons to 42 million tons. Moreover, the reserve margin increases from 42.57% to 65.3%, which make the average electricity generation costs increase from Rpl,OS6. 04/kWh to Rpl,124. 29/kWh.

考虑间歇性可再生能源高比例的苏拉威西电力系统长期扩产规划

为了满足电力需求并确保某些地区的可持续发展，需要进行发电扩展规划(GEP)。GEP在规定的时间范围内优化发电机组的数量、类型、时间和容量，以满足需求。优化过程是在一定的技术约束下使总成本最小化。本文考虑可再生能源的间歇性，确定了苏拉威西电力系统的长期GEP。考虑GEP中的间歇性可再生能源，2050年可再生能源比重可提高9.77%至19.32%，煤炭比重可从75.19%降至61.67%。另一方面是系统的环境效益，年排放量从4580万吨减少到4200万吨。此外，储备边际从42.57%增加到65.3%，这使得平均发电成本从Rpl,OS6增加。4/kWh到Rpl,124。29 /千瓦时。
