Modelling of pumped-storage generation in sequential Monte Carlo production simulation

Power system planning inherently needs to consider all aspects of how a power system may be planned and operated to provide a reliable and economic supply of electrical energy. This includes the need to simulate generation production, particularly the appropriate coordination between thermal and hydro generation. One of the most difficult features of this is the incorporation of limited-energy pumped-storage hydro generation within such simulations. This paper describes a new approach for incorporating pumped-storage units using sequential Monte Carlo simulation. The scheduling is defined as a constrained optimisation problem using a network flow algorithm. The application and benefits of the proposed model are demonstrated using the IEEE reliability test system
