Long Term Planning Model (LTP)

The PLP Model is a computational and mathematical tool that allows solving the problem of medium and long term operation planning in hydrothermal electric systems, determining the setpoints of power plants and reservoirs that minimize the expected value of generation and failure costs and the future value of water, applying the algorithm known as Stochastic Dual Dynamic Programming.

This model was developed since 2004 and is widely used by several companies of the electric sector and the National Electric Coordinator. This organization uses the results provided by the PLP model to determine the weekly scheduling and daily price policies of the National Electric System (SEN), in addition to other medium and long term studies.

Since its implementation, important modifications have been made to the model. The Energy Center has had a relevant participation in all the improvements made to the PLP model. Focused on this aspect, the last projects related to the PLP model in which the Energy Center has participated have consisted in improving its mathematical robustness and computational performance, implementing improvements such as: Multicore processing; Numerical scaling and stability; Compatibility with different optimization engines; Improvements in different formulations of the electrical and hydraulic model, such as: model of reservoirs with multiple outputs, re-formulation of irrigation agreements and treatment of fictitious tributaries by means of feasibility cuts.

For more information about the installation of the PLP model in local servers or in Amazon Web Services, training in the use of this tool and development of case studies (projection of energy matrices, projection of marginal costs per bus, generation per plant and companies, etc.), please send us an email to contacto@centroenergia.cl
