An Enhanced Harmony Search Algorithm for Cascade Reservoirs Planning

Abstract

A fair, efficient, and reasonable strategy for benefit transfer to multistakeholders is critical for preserving cooperation stability and development sustainability for cascade reservoirs under current comprehensive watershed development. This research proposes a novel approach to cascade reservoir planning that considers the need for multi-objective water resource development and benefit distribution to multiple stakeholders. The cascade reservoirs planning is modeled as the optimal dispatching model function and optimized by applying an enhanced harmony search algorithm (EHSA). Compared results with the previous methods show that the proposed method with EHSA produces total power generation higher and the calculation time faster convergence speed respectively than other competitive methods. The proposed method provides a feasible way to solve the optimal dispatching model of cascade reservoir planning in power generators.
