Minimizing Bid Cost Recovery for Energy Storage with Uniform Pricing
Yaxuan Yu, Jingguan Liu, Cong Chen
We study in-market uniform pricing and out-of-market bid cost recovery (BCR) payments in rolling-window dispatch for real-time power system operations with energy storage resources…
Coupling-Aware Aggregation of Multi-Zone HVAC Loads under Uncertainty: A Two-level Framework
Jingguan Liu, Han Jiang, Xiaomeng Ai +6
Aggregating building heating, ventilation, and air-conditioning (HVAC) loads unlocks substantial demand-side flexibility for power systems. Yet multi-zone coupling creates intricat…
Preference-Oriented Aggregation of Heterogeneous Distributed Energy Resources for Reserve Dispatch
Jingguan Liu, Xiaomeng Ai, Shichang Cui +5
Aggregating distributed energy resources (DERs) aims to encode their collective flexibility into a single set for efficient grid dispatch. However, existing aggregation methods are…
Leveraging Time-Causal State Variable Aggregation for Real-Time Schedule of Massive Air Conditioners
Jingguan Liu, Xiaomeng Ai, Shichang Cui +5
Air conditioner (AC) loads offer promising flexibility for active distribution networks to manage uncertainties, such as those in renewable energy generation, electricity prices, a…
Continuous-Time Aggregation of Massive Flexible HVAC Loads Considering Uncertainty for Reserve Provision in Power System Dispatch
Jingguan Liu, Xiaomeng Ai, Jiakun Fang +4
Heating, ventilation, and air conditioning (HVAC) loads, with their rapid response capabilities, can provide considerable intra-hour flexibility on the demand side for reserve prov…
Dimension-Reduced ADP for Real-Time Microgrid Operation with Massive Air-Conditioning Loads under Multiple Uncertainties
Jingguan Liu, Xiaomeng Ai, Shichang Cui +2
This paper proposes a dimension-reduced approximate dynamic programming (ADP) method for real-time microgrid operation with massive air-conditioning loads under multiple uncertaint…
Reachable-Set Decomposition for Real-Time Aggregation of Multi-Zone HVAC Fleets
Jingguan Liu, Xiaomeng Ai, Cong Chen +4
Aggregating building heating, ventilation, and air-conditioning (HVAC) fleets can provide substantial real-time flexibility to power systems. However, practical deployment requires…
Mean-Field Learning for Storage Aggregation
Jingguan Liu, Cong Chen, Xiaomeng Ai +3
Distributed energy storage devices can be aggregated to provide operational flexibility for power systems. This requires representing a massive device population as a single, tract…
