With the advancement of China’s carbon policy, proportion renewable energy, mainly wind and solar, has increased, which brings greater challenges to reservation power systems. Due complexity systems, adopting method zonal reserve ensure stable system operation is very difficult. Among existing clearing results for calculating reservation, unit will be restricted by network security constraints,...

The unit commitment problem is to find the production scheduling of a set of electric power generating units, and the generation levels for each unit, over a short term, typically from 24 hours to one week. The objective is to find the optimal schedule which meets the energy demand forecast at a minimum cost, and satisfy technological constraints such as the minimum up and down times for the un...

We derive extended formulations for the two-stage stochastic unit commitment with reserves. Our approach can capture most physical characteristics of a complicated thermal generator including min-up/-down time limit, time-dependent start-up costs, start-up/shut-down ramping, general ramping in stable region, and reserve amount commitments. The include both convex hull descriptions feasible regi...

This paper presents a novel approach to solve the Multi-Area unit –commitment problem using a evolutionary programming technique. The objective of the Multi-Area unit commitment problem is to determine the optimal or a near optimal commitment strategy for generating units located in multiple areas that are interconnected via tie –lines and joint operation of generation resources can result in s...

Due to the high randomness and volatility of renewable energy sources such as wind energy, traditional thermal unit commitment (UC) model is no longer applicable. In this paper, in order reduce possible negative effects an inaccurate forecast, chance-constrained programming (CCP) method used study UC problem with uncertainty power generation, chance constraints balance spinning reserve are sati...
