英文摘要:
Hydro storage system optimization is becoming one of the most challenging tasks in Energy Finance. While currently the state-of-the-art of the commercial software in the industry implements mainly linear models, we would like to introduce risk aversion and a generic utility function. At the same time, we aim to develop and implement a computational efficient algorithm, which is not affected by the curse of dimensionality and does not utilize subjective heuristics to prevent it. For the short term power market we propose a simultaneous solution for both dispatch and bidding problems. Following the Blomvall and Lindberg (2002) interior point model, we set up a stochastic multiperiod optimization procedure by means of a \"bushy\" recombining tree that provides fast computational results. Inequality constraints are packed into the objective function by the logarithmic barrier approach and the utility function is approximated by its second order Taylor polynomial. The optimal solution for the original problem is obtained as a diagonal sequence where the first diagonal dimension is the parameter controlling the logarithmic penalty and the second is the parameter for the Newton step in the construction of the approximated solution. Optimal intraday electricity trading and water values for hydro assets as shadow prices are computed. The algorithm is implemented in Mathematica.

中文摘要:
储能系统优化正成为能源金融领域最具挑战性的任务之一。虽然目前业界最先进的商业软件主要实现线性模型,但我们希望引入风险规避和通用效用函数。同时,我们的目标是开发和实现一种计算效率高的算法,该算法不受维数灾难的影响,也不使用主观启发式来防止维数灾难。对于短期电力市场,我们提出了一种同时解决调度和竞价问题的方法。根据Blomvall和Lindberg(2002)的内点模型,我们通过一个“浓密”的重组树建立了一个随机多周期优化过程,该树提供了快速的计算结果。利用对数障碍法将不等式约束压缩到目标函数中,利用二阶泰勒多项式逼近效用函数。原始问题的最优解以对角序列的形式获得,其中第一对角维数是控制对数惩罚的参数,第二对角维数是构造近似解的牛顿步的参数。计算了作为影子价格的水电资产的最佳日内电力交易和水价。该算法在Mathematica中实现。
