摘要: 微网储能系统对于充分利用可再生能源、提高微网经济效益发挥着重要作用,为实现经济利润的最大化,需采取合理有效的储能策略。在考虑电价不确定性和波动性的基础上,建立决策过程的目标函数,并提出通过储能系统实现利润最大化的动态规划模型。研究结果表明,采用该模型能更好地推进储能技术发展,提供更大的利润空间。以一个微网储能系统为例,分析价格和储能策略对系统利润的影响,验证了所建立模型的可行性和合理性。

Abstract: Energy storage systems play an important role in taking full advantage of renewable energy and improving the economic benefits of microgrids. Effective energy strategies need to be applied to realize the profit maximization. Considering the uncertainty and volatility of the electricity prices, the objective function of decision-making process is established, and the dynamic programming model to maximize the profits by energy storage systems is presented. The results show that the model can promote the development of energy storage technologies and provide greater profit margins. The impacts of price and energy storage strategy on the profits are analyzed by taking an energy storage system in microgrid as an example, and the feasibility and rationality of the proposed method are proven.

Key words: microgrid, energy storage system, profit maximization, dynamic programming
