短期可再生能源供应波动下的最优电力消费与储存
Optimal electricity consumption and storage under short-term renewable supply variability
摘要
The expansion of intermittent renewable electricity increases supply variability and requires greater flexibility from consumers. This results in welfare losses for agents who are averse to fluctuations. Our model analyzes these welfare consequences by considering short-term and exogenous variability in renewable energy generation. We explore an optimal control problem that determines a welfare-maximizing electricity consumption path by controlling dispatchable energy and storage. This optimization problem identifies three scenarios: no active storage, abundant storage capacities and limited capacities. We then derive an overall consumer welfare function for alternative energy mixes. This allows us to assess the welfare effects of changing the energy mix. In particular, we consider the substitution of dispatchable fossil-fueled energy generation by renewable energy.
中文摘要
间歇性可再生电力的扩张增加了供给的可变性，并要求消费者具备更大的灵活性。这给厌恶波动的行为主体带来了福利损失。我们的模型通过考虑可再生能源发电的短期和外生可变性来分析这些福利后果。我们探讨了一个最优控制问题，通过控制可调度能源和储能来确定福利最大化的电力消费路径。该优化问题识别出三种情景：无主动储能、储能容量充裕以及容量有限。随后，我们为不同能源组合推导出一个总体消费者福利函数。这使我们能够评估改变能源组合的福利效应。特别地，我们考虑了以可再生能源替代可调度化石燃料发电的情形。
