Public welfare energy storage system knowledge promotion

Can community energy storage improve social welfare?

As a price maker, the community energy storage can not only earn profits through energy arbitrage but also smooth price trajectories and further influence social welfare. We formulate the problem as a finite-horizon Markov decision process that aims to maximize the energy arbitrage and social welfare of the prosumer-based community.

How a government can promote energy storage technology?

Energy storage technology is the key technology to promote the consumption of renewable energy. The government can promote the energy storage technology through the incentive policy of energy storage industry.

Can energy storage technology be promoted under incentive policies?

In a certain sense, this study reveals the research on the promotion mechanism of energy storage technology under incentive policies and provides a certain reference basis for local governments to formulate and improve energy storage policies.

How does energy storage affect consumer welfare?

With the growing scale of energy storage, the welfare benefits become significant, which may stimulate different ownership, such as consumers, producers and prosumers, to focus on their own welfare, thus further influencing storage use. In particular, consumers are likely to increase consumer surplus, so they tend to overuse storage.

Does welfare maximizing storage earn more benefits than profit-maximizing storage?

Case studies indicate that welfare-maximizing storage earns more benefits than profit-maximizing storage. The proposed threshold-based algorithm can guarantee optimality and largely decrease the computational complexity of standard stochastic dynamic programming.

What is community energy storage?

Background and motivation Community energy storage is one of the advanced smart grid technologies in recent years, which provides lots of benefits for the electric power system in reliability, quality, economy and control .
