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 .

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.

Do thermal power units participate in peak regulation auxiliary services?

Owing to China’s energy structure, thermal power accounts for nearly half of the country’s installed power generation capacity. Although the willingness of thermal power units to participate in peak regulation auxiliary services is low, we propose a peak regulation cost compensation and capacity-proportional allocation mechanism.

Can battery energy storage system be used for frequency and peak regulation?

Some scholars have made lots of research findings on the economic benefit evaluation of battery energy storage system (BESS) for frequency and peak regulation. Most of them are about how to configure energy storage in the new energy power plants or thermal power plants to realize joint regulation.

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.
