本文研究了输电线路和储能系统的联合投资规划问题。储能可被视为输电基础设施的补充，可用于输电延迟。另一方面，在一定条件下，当两个部门的预期利润取决于系统中的拥塞时，输电和储能可以被视为竞争对手。在本研究中，输电部门被假设为自然垄断，输电线路的运营和规划由独立公司进行，而储能所有者公司则在竞争性市场规则下运营和投资。本文主要讨论三个问题。首先，额外的储能容量会有助于社会福利的增长吗？其次，输电网络的激励性监管将如何影响储能需求？第三，激励性监管的选择将如何影响储能的价值。本文首先概述了可应用于输电投资的激励性监管。然后，基于6节点电力系统网络和IEEE 118节点系统的案例研究，以回答上述问题。案例研究的结果表明，储能投资补充了输电扩张，并有助于提高社会福利价值。与没有激励性监管的情况相比，在两种研究的激励性监管下，储能投资的收益显着更高。因此，输电投资规划过程应考虑储能选项。
This paper investigates joint investment planning of transmission lines and energy storage. Energy storage can be seen as a complement to transmission infrastructure and can be used for transmission deferral. On the other hand, under certain conditions, when the expected profit of both sectors depends on congestion in the system, transmission and energy storage can be seen as competitors. The transmission sector is in this study assumed to be a natural monopoly and operation and planning of transmission lines is performed by an independent company whereas the energy storage owner company operates and invests under competitive market rules. Three main questions are addressed in this paper. First of all, will additional energy storage capacity contribute to the growth of social welfare? Second, how will incentive regulation of the transmission network affect the need for energy storage? Third, how will the choice of incentive regulation affect the value of energy storage. This paper first provides an overview of incentive regulation which can be applied to transmission investments. Then case studies based on a 6-node power system network and the IEEE 118-node system are proposed in order to answer the aforementioned questions. The results of the case studies show that energy storage investments complement transmission expansion and contribute to higher social welfare values. The benefits from energy storage investments are significantly higher under two investigated incentive regulations as compared to the case without incentive regulation. Thus, the transmission investment planning process should consider energy storage options.
