CEVESA is a dynamic generation expansion planning model for the Spanish power system (assumed as a single-node), that considers both investments made by distributed customers in Distributed Energy Resources (DER: generation and storage) and by generation companies (GENCOs) in Centralized Resources (CR: conventional thermal generation plants, renewable generation and centralized storage). It is also connected with the transport sector by including investments decisions on Electric Vehicles (PEV) and Internal Combustion Engine Vehicles (CEV), considering infrastructure deployment, fuel, and social and environmental costs of both technologies. The model is based on a conjectural-variation equilibrium with price-response conjectures with hourly detail, energy and endogenous secondary reserve requirements, ramping constraints, and start-ups and shut-downs. The equilibrium model is a one-only level model for both investment and operation decisions, solved using an equivalent quadratic minimization problem, which simplifies its resolution.
In the power system GENCOs maximize their profits while customers minimize their energy bill considering tariffs and DER investments, being both problems linked by the hourly energy balance and the coverage constraint of the yearly peak demand to guarantee generation capacity for the security of supply. In addition:
In the transport sector:
