Robust Optimal Coordinated Charging Bidding of Ancillary Services for the Vehicle to Grid in Regulation and Spinning Reserve Markets

Vehicle to grid (V۲G) is one the most important ways to effectively integrate electric vehicles (EVs) with electric power systems. The important benefits can be made by V۲G such as reducing/increasing the cost/revenue of EV owners and technically sup-porting electric power systems. Concerning technical and regulatory constraints, EV owners must participate in electricity mar-kets via aggregators. This paper proposes a robust optimal coordinated charging (OCC) model including bidding ancillary ser-vices for regulation and spinning reserve markets. The presented work handles the uncertain behavior of the electricity market that are ancillary service prices and their deployment signals by the robust optimization approach. The aim of optimization is the maximization of the aggregator’s profits from V۲G by joining the ancillary services markets. The recommended robust OCC model which is a robust linear problem (RLP) model is simulated by the CPLEX solver in GAMS software. An assumed set of ۱۰۰۰۰ EVs in the electric reliability council of Texas (ERCOT) electricity markets is considered for doing simulations.  Employ-ing the presented model in this test system shows the efficacy of the proposed model in comparison to other deterministic and stochastic models.
