摘要：

Clean energy strategy presented highlights the importance of the system's power balance and scheduling optimization studies with high proportion of hydropower. Based on the hydrological characteristic and hydropower generation characteristic, hydropower conversion curve's piecewise linear function was fit. By introducing auxiliary 0-1 variables, this paper proposed two methods, that were repulsion technique and right valuation technique, to build a mixed integer quadratic programming (MIQP) model containing six kinds of 0-1 variables, which considered the connection of water and electricity, water and electricity coupling relationship respectively in geography and time, hydropower and thermal power's coordination peaking capacity as well as hydropower units' oscillation interval constraints. Finally, adopt dynamic heuristics algorithm (DHA) and active set cutting plane method (ASCPM) with the mixed integer programming solver for a test system to verify the model. The simulation results demonstrate the model and algorithm proposed is capable of handling high proportion of hydropower's system power balance problem and gets the scheduling optimization plan effectively. © 2017 Chin.
