Optimizing Operation Strategy in a Simulated High-Proportion Wind Power Wind–Coal Combined Base Load Power Generation System under Multiple Scenes

In order to accommodate more intermittent renewable energy in coal-dominated power systems, conventional thermal plants need improve their operational flexibility balance the system at all times. However, flexible operation of coal-fired could reduce efficiency and increase CO2 pollutant emission, so it is important consider environmental implications optimize dispatch wind coal units system. this paper, based on output profile power, a peak (T, H) simulation model Gaussian distribution was established. Using high-proportion wind–coal combined base load generation as an example, economical environmentally friendly unit different penetration studied by simulation, decision strategy Wind curtailment boundary determined with cost, consumption, emissions targets, respectively. Weekly scale results indicate that incorporating consumption into consideration will lead decision-making strategies compared only targeting minimizing curtailment. This paper established economy criteria. work directly contributes real great significance for future scheduling/dispatch studies actual systems.
