Hydrothermal scheduling in the continuous-time framework

Electric Power Systems Research, 2020
Continuous-time optimization models have successfully been used to capture the impact of ramping limitations in power systems. In this paper, the continuous-time framework is adapted to model flexible hydropower resources interacting with slow-ramping thermal generators to minimize the hydrothermal system cost of operation.

Influence Types of Startup on Hydrothermal Scheduling [PDF]

TELKOMNIKA (Telecommunication Computing Electronics and Control), 2018
The energy costs of a power plant consist of startup cost and cost of power usage. In contrast to the existing literature, this study introduces at startup cost based on the duration of thermal power plant downtime. The approach of startup cost function in this research is done by using startup type.
