Abstract:The power industry reform in China brings new challenges for the security and stability operation of the power system in hydro-dominated electricity markets. In this study, an integrated method is presented for verifying the feasibility and the executability of the contracted generation formed in the Power Exchange. The integrated method consists of four parts: first to forecast the inflows of large hydropower plants, and then evaluate their generation capacities, compared with their contracted generation. After that, monthly load curve is forecasted with hourly time intervals. Finally, an improved load shedding method is proposed in power and energy balance analysis to determine whether the balance of system will achieve. The proposed method is effective and efficient for verifying the feasibility and the executability of the contracted generation, and it is an important ex ante measure for ensuring the security and stability operation of the power system, as demonstrated in the real case study.
