摘要
中长期电网规划具有许多不确定因素,采用通常的确定性规划模型和算法,难以获得满意的实用规划方案。建立在Garver等人提出的灵敏度分析方法基础上,提出了一种灵活电网规划的概念和模型,可以计及各种规划环境变化因素对方案的影响,通过补偿线性规划算法进行选代求解,最终经过风险决策评判获得满意的适应性规划方案,从而为求解不确定条件下的电网优化问题探索了一条新的途径。通过一个简化了的实际系统算例,表明了该方法的可行性和有效性。
Medium-long term power network planning has to handle many uncertain constraint factors. but some availablestandard optimization models can not resolve this problem. For the sake of it. this paper expounds a new flexible strategyconcept and its model and algorithm for transmission system expansion under multi scenario forecasting. which can permitplanners to find optimal flexible alternatives facing uncertainty. The solution approach is based on stochastic linear programswith recourse and risk decision criteria. This method demonstrates remarkable merits on dealing with some uncertainconstraints. A case study with a simplified power system is presented and discussed.
