Integrated Unit Commitment and Natural Gas Network Considering the High Solar Penetration
In this paper, the integrated unit commitment problem and gas network operation in which in the presence of renewable wind and solar power plants is modeled. Both wind and solar energy are variable sources of energy, but because solar energy is only available at certain times of the day, it has caused the load curve behavior to change. This change in load curve, known as the "duck curve, has ra...

متن کاملLagrangian Relaxation Neural Network for Unit Commitment
This paper presents a novel method for unit commitment by synergistically combining Lagrangian relaxation for constraint handling with Hopfield-type recurrent neural networks for fast convergence to the minimum. The key idea is to set up a Hopfieldtype network using the negative dual as its energy function. This network is connected to “neuron-based dynamic programming modules” that make full u...
متن کاملUnit Commitment With Probabilistic Reserve
This paper demonstrates how a probabilistic criterion based on the full capacity outage probability distribution (e.g., LOLP) could be integrated into the unit commitment (UC) optimization using simple statistical approximation. While this provides a direct and computationally cheaper means as compared to a recently published approach to locating the globally optimal SR allocation (and associat...
متن کاملUnit commitment with valve-point loading effect
Valve-point loading affects the input-output characteristics of generating units, bringing the fuel costs nonlinear and nonsmooth. This has been considered in the solution of load dispatch problems, but not in the planning phase of unit commitment. This paper presents a mathematical optimization model for the thermal unit commitment problem considering valve-point loading. The formulation is ba...
