The energy storage model is a good method to deal with these characteristics, and there have been several papers that propose energy storage models for TCLs [12,13,14,15,16,17]. Regarding the inverter air conditioner, a thermal battery model is established for the power dispatch model in [ 12 ].
Background and model features2.1. Virtual energy storage. Commonly, ... the system energy price is set to that price. And during peak load hours h8-h22, the VES discharges and strategically offers the price that is equal to the offer price of the marginal unit. Thus, the VES makes profits through energy arbitrage and can exert strategic ...
As such, the generic and ideal energy storage model [3] is among one of the most used linear model for power system operation and planning analysis. Apart from the accuracy issues for using linear models, it is still missing an explicit formulation for accounting ...
