Determination of weak points based on risk theory and application to transmission network planning

In the traditional power transmission network planning,deterministic analysis methods are widely used.In such methods,all contingencies are deemed to have the same occurrence probability,which is not reasonable.In this paper,risk assessment is introduced to the process of transmission network planning considering the probabilistic characteristics of contingencies.Risk indices are given to determine the weak points of the transmission network based on local information,such as bus risk,line overload risk,contingency severity.The indices are calculated by the optimal cost control method based on risk theory,which can help planners to quickly determine weak points in the planning and find solution to them.For simplification,only line overload violation is considered.Finally,the proposed method is validated by an IEEE-RTS test system and a real power system in China from two aspects.In the first case,the original system is evaluated by the proposed method to find the weak points,and then four planning schemes are established,among which the best scheme is selected.In the second case,four initial planning schemes are established by combining the experiences of planners,and after the evaluation by using the proposed method,the best planning scheme is improved based on the information of weak points in the initial schemes,and the risk of improved scheme is reduced from 42 531.86 MW·h per year to 4 431.26 MW·h per year.     

盐城市老城区静态交通现状调研

在人口密集的老城区,中高档的商品交易市场及社会公共服务设施也相对集中,可是只有在大型商场才设有地下停车场,虽能安置部分消费者的车辆,但是停车位的数量根本无法满足广大居民的需求且进入停车场多需穿过密集人群,实多不便。导致有不少车辆在泊车是占用了自行车道及人行道的空间,以致交通多滞。机动车道临时停车位的较小密度以及公共汽车站台的乘客容纳量,经常给出入老城区的居民带来诸多不便,导致交通滞塞。
