Price adjustment for public welfare energy storage system

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.

Is opportunity pricing a social welfare maximization objective for energy storage?

k: We propose a novel opportunity pricing design for energy storage with a social welfare maximization objective while guaranteeing robust competitive equilibrium. Opportunity price is derived from a chance-constraine

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.

Does storage exercise greater market power?

What is the 2022 cost and performance assessment?

The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations. In September 2021, DOE launched the Long-Duration Storage Shot which aims to reduce costs by 90% in storage systems that deliver over 10 hours of duration within one decade. The analysis of longer duration storage systems supports this effort.
