In the energy management of the isolated operation of small power system, the economic scheduling of the generation units is a crucial problem. Applying right timing can maximize the performance of the supply. The optimal operation of a wind turbine, a solar unit, a fuel cell and a storage battery is searched by a mixed-integer linear programming implemented in General Algebraic Modeling System...

Hydro generation scheduling is a nonlinear programming problem. This paper describes the hydro generation scheduling problem constraints. The optimal hydro scheduling problem is formulated as a large scale linear programming algorithm and is solved using a commercially available linear programming package. The selected objective function requires minimization of demand and generation of a hydro...

The problem of wind power abandonment in the north areas China is serious, which mainly caused by uncertainty and "thermoelectric coupling" characteristics cogeneration units. Aiming at this problem, paper establishes optimal scheduling model generation-load-storage coordination electrothermal joint system with goal minimizing amount discarded total cost system. Firstly, responsive electrical t...

There are many methods for overload relieving which have been reported for determining a secure operating point. Most of these methods use conventional optimization techniques, which are generally time–consuming from a computation point of view, especially for large systems. Further the conventional optimization technique updates all the controllers for most of the operating conditions. Under e...

The proportion of renewable power generation in the world has been increasing recent years. However, fluctuations and uncertainties bring a considerable challenge to future unit scheduling. Therefore, flexibility systems becomes more critical as large amount is integrated into systems. use flexible generators with energy storage one most efficient methods improving system flexibility. primary p...

There has been a global effort to reduce the amount of greenhouse gas emissions. In an electric resource scheduling, emission dispatch and load economic dispatch problems should be considered. Using renewable energy resources (RESs), especially wind and solar, can be effective in cutting back emissions associated with power system. Further, the application of electric vehicles (EV) capable of b...

The optimal scheduling or unit commitment of power generation systems to meet a random demand involves the solution of a class of dynamic programming inequalities for the optimal cost and control law. We study the behavior of this optimality system in terms of two parameters: (i) a scheduling delay, e.g., the startup time of a generation unit; and (ii) the relative magnitudes of the costs (oper...
