摘要
针对风光资源都比较丰富的北方某试点乡的实际气象数据和负荷数据,基于可再生能源混合优化模型HOMER(hybrid optimization model for electric renewables)设计软件平台,建立并优化了风光蓄发电系统、独立柴油发电机系统及二者的混合系统3种孤网模型。在满足各项约束、负荷可靠供电及各微电源成本的基础上,将环境保护、社会效益以及用户效益分别对应量化为排污惩罚成本、容量短缺成本和实际停电率等指标。以最小上述指标为目标进行综合评估,对比了3种不同规划方案的利弊,从而得出了适合该地区的最优方案。
Aiming at the actual meteorological data and load data of a northern pilot township of abundant in wind and solar resource, three models are constructed and optimized： standalone diesel system, PV-WT battery system and hy- brid system. On the basis of meeting the constraints, reliable power supply and counting for the cost of each mi- crosource, environmental protection, social benefits and user benefits are quantified into the indexs of emission penalty cost, capacity shortage and actual outage rate correspondingly. Comprehensive assessments are used to minimize the net present cost （NPC）, the cost of energy （COE） and the emissions, and the three models are built and compared in HOMER（hybrid optimization model for electric renewables ） to get the optimal case to appropriate for the region.
