Research Initiation Award:Parallel Computation for Large- Scale Hydrothermal Generation Scheduling Problems.

该项目涉及机组组合和水热调度领域。这些问题是复杂的，因为它们的规模大、混合(整数和实数)变量、非线性和不确定性。将开发一种新的算法。热力子问题和水力子问题的处理方式不同。对于热力子问题，机组组合部分采用拉格朗日关系求解，避免了量纲问题，而发热量的计算则用解析的方法求解。水力子问题将进一步分解为多个独立子问题，并利用约束松弛差分动态规划进行并行求解。这种方法声称有许多优点。如果成功，该方法不仅将产生可观的经济效益，而且还将推进大规模优化领域的最新技术。

This project is in the area of unit commitment and hydrothermal scheduling. These problems are complicated because of their large size, mixed (integer and real) variables, nonlinearity, and uncertainty. A new algorithm will be developed. The thermal and hydro subproblems are handled differently. For the thermal subproblem, the unit commitment part will be solved using Lagrange relation to avoid the dimensionality problem, while the calculation of thermal generation is solved analytically. The hydro subproblem will be further decomposed into a number of independent subproblems, and will be solved in parallel by using constraint relaxed differential dynamic programming. There are many advantages claimed for this approach. If successful, the method will not only yield substantial economic benefits, but will also advance the state of the art in the field of large-scale optimization.
