Abstract
In this paper, a method on evaluation of annual accommodation ability of high renewable energy penetrated power system with cascaded hydro power plants is proposed. Firstly, an aggregated cascaded hydro power operation model is established and a long-term unit commitment model with cascaded hydro power, thermal, wind and photovoltaic (PV) plants is formulated. The objective of the formulated model is maximizing the power generation of renewable energy, and constraints of load balance, system reserve, and operations of each power plants are considered. Secondly, the hourly power series of renewable energy is incorporated as inputs which contain theoretic power outputs of wind, PV and natural water inflows of each cascaded hydro power plant. Thirdly, a monthly sequential decomposition algorithm is adopted to solve the long-term unit commitment model. Finally, the proposed method is tested on a high renewable energy penetrated power system with large-scale wind, PV and cascaded hydro power. Testing results indicate the effectiveness and applicability of the proposed method.
