6 FAQs about [Power generation side energy storage peak regulation subsidy]

Why do we need power generation-side energy storage systems?

However, the power system is facing the problem of deteriorating power quality and decreasing power security level due to the volatility and randomness of renewable energy generation . Power generation-side energy storage systems (ESS) with a fast response rate and high regulation accuracy have become essential to solving this problem .

Why is peak-regulation insufficiency a problem in urban power grids?

In recent years, the power load as well as the peak–valley load difference has increased greatly, causing the shortage of peak-regulation capacity in urban power grids. Furthermore, with the increasing penetration of renewable energy generation (Ahmad et al., 2021), the peak-regulation insufficiency issue becomes even more serious and complicated.

Does subsidy retraction affect sequential investment in energy storage?

A real options model for sequential investment in energy storage is developed. Policy uncertainty of subsidy retraction, provision or transformation is considered. Sequential investment promotes earlier project deployment than lumpy investment. Retraction has a greater impact on investment than the provision of subsidies.

What is peak-regulation capability of a power grid?

Principle of the evaluation method The peak-regulation capability of a power grid refers to the ability of power supply balancing with power load, especially in the peak load and valley load periods. Specifically, the adjustment range of power supply in one day should be high enough to reach the peak load and low enough to reach the valley load.

Do investors invest in generation-side ESS projects under electricity price and subsidy policy uncertainties?

The study considers investors' continuous capacity investment in generation-side ESS projects under both electricity price and subsidy policy uncertainties. Assume that the ESS project has an installed capacity of q and is gradually completed through n stages of sequential investment.

Do increased subsidies incentivize investment if subsidies are retracted?

Increased subsidies do not incentivize investment when subsidies may be retracted. Energy storage systems (ESS) are crucial for addressing the intermittent nature of renewable energy, and improving the flexibility of power systems. However, the uncertainties in the investment decision process pose a challenge for investment evaluation of ESS.
