In electrical grids with a high renewable percentage, weather conditions have greater impact on power generation. This can lead to the overproduction of electricity during periods substantial wind generation, resulting in shutoffs turbines. To reduce such and bridge lower production, three thermal energy storage systems (TESs) been developed for space heating domestic hot water. These include w...
This paper presents new solution methods and results based on a refined binary particle swarm optimization (RBPSO) for solving the generation/pumping scheduling problem within the power system operation with pumped-storage units. The proposed RBPSO approach combines a basic particle swarm optimization (PSO) with binary encoding/decoding techniques. Complete solution algorithms and encoding/deco...
The aim of this paper is to present short-term hydrothermal scheduling (STHS) of power system. This problem is solved in such a way that utilizes available hydro reserves optimally and thus minimizes the fuel cost of thermal plants. A PSO based method is developed which can efficiently deals with hydro constraints like reservoir storage volume limits, water discharge rate limits, water dynamic ...
This paper presents an effective solution for the short-term hydrothermal generation scheduling (STHS) problem using integration of wind and photovoltaic power (PV) system. Wind PV are integrated into system to minimize total fuel cost thermal units. In this paper, lightning attachment procedure optimization algorithm (LAPO) is employed solve STHS The proposed method applied solving five test s...
The short term cost optimal dispatch of electric power in a generation sys tem under uncertain electricity demand is considered The system comprises thermal and pumped storage hydro units An operation model is developed which represents a multistage mixed integer stochastic program and a conceptual solution method using La grangian relaxation is sketched For xed start up and shut down decisions...
Bi-objective problem; Hydrothermal scheduling; Economic dispatch; Emission dispatch; Combined economic emission dispatch Abstract The short-term combined economic emission hydrothermal scheduling is a bi-objective problem minimizing both fuel cost and emission of a hydrothermal system while satisfying thermal, hydro and system constraints. In this paper, an efficient cuckoo bird-inspired meta-h...
the proposed method, the profit maximization problem is transformed into a minimization problem that can be solved by a traditional hydro-thermal unit commitment program after implementing a few modifications. The paper describes t he modifications introduced in a unit commitment program based on the Lagrangian relaxation approach and on a disaggregated Bundle method for the solution of the dua...
