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 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 storage reduce social welfare?
The cases in which storage reduces social welfare can be unexpected, insomuch as adding firms to an imperfectly competitive market typically improves allocative efficiency. Moreover, these findings are different from those of Sioshansi et al. (2009) who also examine storage use with responsive prices, but do not find welfare losses.
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 .
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.
Can strategic storage yield social welfare losses?
By definition, δC,C cannot result in social welfare losses compared to not having storage, since δC,C = 0 is feasible and δC,C is welfare-maximizing. To show that strategic storage cannot yield social welfare losses, note that δS,C > 0 if and only if: p 2 0 − η p 1 0 = W ′ 0 > 0.
