In this paper, the Economic Power Dispatch (EPD) of the thermal power plants in Iraq is studied. The main goal of this study is to minimize the high fuel costs of the Iraqi power generation system by controlling the outputs for each generating unit via the optimization algorithms. Though the Iraqi network is composed of the total 31 thermal units, it is considered as a large-scale system, and the...
The Short-Term Hydrothermal Scheduling (STHTS) is one of the most prominent exercise in the field of power system. It advocates the scheduling of hydro and thermal generations so as to minimize the fuel cost over the planning period by satisfying standard system constraints. The problem of scheduling of a generation mixture of thermal and hydro problems are modelled as a non linear, non convex problems...
In this paper, two control strategies involving "continuous" and "ON/OFF" operation of the diesel generator in the battery-integrated hybrid system are developed, implemented and compared. The main purpose of these modeled controlled strategies is to minimize the diesel generator operation cost in standalone electricity generation processes. The simulations have been performed...
Economic Load Dispatch (ELD) is one of the important optimization problem in advanced power system and control. In this paper, six and fifteen generating units in ELD problem has been considered. Prohibited zone and ramp rate limit constraints has been also considered. ELD problem has been solved using three types of optimization techniques. These optimization techniques are Particle Swarm Optimization...
In this paper an Economic Emission Dispatch (EED) problem is proposed to investigate the emission control. The current energy consumption is weighing heavily on fossil fuels which account for about 70–90% of total energy used. These fossil fuels produce harmful gaseous emissions such as nitrogen oxides (NOx), sulphur dioxide (SO2) and carbon dioxide (CO2) which cause hazardous effects in the atmosphere...
Combining solid oxide fuel cell and gas turbine (SOFC/GT) system is a promising concept for future clean and efficient power generation. An SOFC/GT system exploits the complementary features of the two power plants, where the GT recuperates the energy in the SOFC exhaust stream and thereby boosting the overall system efficiency. Through model based transient analysis, however, it is shown that the...
This paper demonstrates that the incorporation of optimally-rated energy storage units and renewable generators into a remote microgrid, in conjunction with an optimal dispatching strategy, can result in substantial reduction in the microgrid lifetime cost and emission. The application of such a microgrid can be in the electrification of off-grid remote communities which, typically, heavily depend...
This paper demonstrates that optimal selection of renewable power generators and energy storage devices in a grid-connected micro-grid, in conjunction with an optimal dispatch strategy, can significantly reduce the micro-grid lifetime cost and emission. The paper presents a mathematical model and optimization algorithm to identify the optimal micro-grid configuration (in terms of the installed capacities...
A new class of meta-heuristics called SOMA (Self-Organizing Migrating Algorithm) was proposed in recent literature. SOMA works on a population of potential solutions called specimen and it is based on the self-organizing behavior of groups of individuals in a ??social environment??. This paper proposes a modified SOMA approach to solving the economic load dispatch problem of thermal generators with...
