Wholesale Market Participation of Storage with State-of-Charge Dependent Bids

no code implementations8 Oct 2022 Cong Chen, Lang Tong

Wholesale market participation of storage with state-of-charge (SoC) dependent bids results in a non-convex cost in a multi-interval economic dispatch, which requires a mixed-integer linear program in the market clearing.

Convexifying Market Clearing of SoC-Dependent Bids from Merchant Storage Participants

no code implementations5 Sep 2022 Cong Chen, Lang Tong

State-of-charge (SoC) dependent bidding allows merchant storage participants to incorporate SoC-dependent operation and opportunity costs in a bid-based market clearing process.

Pricing Energy Storage in Real-time Market

no code implementations25 Jan 2021 Cong Chen, Lang Tong, Ye Guo

It is also shown that such settlements give rise to disincentives for generating firms and storage participants to bid truthfully, even when these market participants are rational price-takers in a competitive market.

Regioned Episodic Reinforcement Learning

no code implementations1 Jan 2021 Jiarui Jin, Cong Chen, Ming Zhou, Weinan Zhang, Rasool Fakoor, David Wipf, Yong Yu, Jun Wang, Alex Smola

Goal-oriented reinforcement learning algorithms are often good at exploration, not exploitation, while episodic algorithms excel at exploitation, not exploration.
