This paper provides several useful support tools of power system scheduling and planning. First, the authors proposed a fast method, which is used to evaluate the generating units and transmission capability of power system, and calculate the optimal reserve of each demand side, based on two-step linear programming technique. Then, a new support tool of power system planning is described by using the parametric linear programming. The proposed support tool does not only fast give a optimal reserve curve of the system, but also provides some diagnosis information of system weak location for the expansion planning and maintenance scheduling decision of transmission lines or generating units. Third, the authors take into account the outages of generators and transmission lines, and show a possible method to estimate the reliability (LOLP) of multi-area power system by making use of linear programming. Several examples have been used to verify the proposed methodology and illustrated the application. The results show that our approaches are very simple, fast and efficient for the generation and transmission capability evaluation or the contingency test of power system as support tools.
