By solving for the investment threshold and investment opportunity value under various uncertainties and different strategies, the optimal investment scheme can be obtained. Finally, to verify the validity of the model, it is applied to investment decisions for energy storage participation in China's peaking auxiliary service market.
The large-scale development of energy storage technologies will address China’s flexibility challenge in the power grid, enabling the high penetration of renewable sources. This article intends to fill the existing research gap in energy storage technologies through the lens of policy and finance.
The expected value of the first energy storage technology, including the embedded option, is Φ 1 (P). In State (1,2), the second energy storage technology arrives with a Poisson process, and the firm invests in the second technology at the optimal time. The investment opportunity value of the second energy storage technology is F1,2 (P).
Under the continuous investment strategy, the firm can invest in two energy storage technologies sequentially, and each state is subject to policy uncertainty. Fig. 4 indicates the different states of the continuous investment strategy and the corresponding value functions under policy uncertainty.
This study assumes that, in the face of multiple uncertainties in policy, technological innovation, and the market, firms can choose to invest in existing energy storage technologies or future improved versions of the technology to generate revenue.
For current energy storage technologies, the continuous strategy can significantly shorten the investment timing and enable investors to adopt the storage technology as early as possible; therefore, when new technologies are unavailable, the continuous investment strategy is the best choice.

Demand-side response (DR) and energy storage system (ESS) are both important means of providing operational flexibility to the power system. Thus, DR has a certain substitution role for ESS, but unlike DR, ESS planning has a coupling relationship between years, which makes it difficult to guarantee the reasonableness of the ESS planning results by …
