与使用传统能源相关的环境问题和燃料成本的不确定性导致连接到配电网的风能数量快速增长。然而，根据安大略省的标准报价计划（SOP），公用事业公司有权限制（泄漏）风能，以避免违反系统限制。这意味着风能产量的任何增加超过特定限制都可能会导致风能削减量的增加。尽管成本高昂，但储能系统（ESS）被认为是解决该问题的可行方案。本文提出了一种在风能渗透率较高的配电系统中分配 ESS 的方法。最终目标是通过调整 ESS 的规模来容纳所有泄漏的风能，然后在系统内进行分配，以最大限度地降低年度电力成本，从而最大限度地提高 DG 所有者和公用事业公司的利益。此外，还进行了成本/效益分析，以便从公用事业公司和 DG 所有者的角度验证安装 ESS 的可行性。
Environmental concerns and fuel cost uncertainties associated with the use of conventional energy sources have resulted in rapid growth in the amount of wind energy connected to distribution grids. However, based on Ontario's standard offer program (SOP), the utility has the right to curtail (spill) wind energy in order to avoid any violation of the system constraints. This means that any increase in wind energy production over a specific limit might be met with an increase in the wind energy curtailed. In spite of their cost, energy storage systems (ESSs) are considered to be a viable solution to this problem. This paper proposes a methodology for allocating an ESS in a distribution system with a high penetration of wind energy. The ultimate goal is to maximize the benefits for both the DG owner and the utility by sizing the ESS to accommodate all amounts of spilled wind energy and by then allocating it within the system in order to minimize the annual cost of the electricity. In addition, a cost/benefit analysis has been conducted in order to verify the feasibility of installing an ESS from the perspective of both the utility and the DG owner.
