Online Training - Economic Dispatch

Dilihat 1522

DESCRIPTION The operation of a power plant is highly dependent on fuel, thus it needs special attention, because most of the operating costs incurred are for fuel purposes. The fuel cost of a generation unit is a generation function. Heavy loads that burden the electrical energy system, so that it always causes a large load that is generated must be equal to the needs on each side. In thermal generating units that use fossil fuels, the increase in load will encourage an increase in the quantity (amount) of fuel per unit time which will increase the cost increase per unit time. Fluctuations in the demand for electrical energy on the load side will cause fluctuations in fuel costs, related to this, it is necessary to determine the correlation between the two, which is commonly called the input output of power plants. In addition, the electricity load is a function of the generation cost, so it is necessary to find a solution to operate the generating units optimally by reducing fuel costs to a minimum and maintaining continuity of service to consumers while still paying attention to operational constraints. This is also known as economic dispatch (EcD). With the application of economic dispatch, a minimum generation cost will be obtained for the production of electrical power generated by generating units in an electrical system. Another problem that has an important role in the amount of power generated by each generating unit is emissions. Each operating thermal generating unit can produce emissions such as nitrogen oxides (NOx), carbon dioxide (COx), and sulfur oxides (SOx) which spread to the environment. Thus, it is necessary to minimize the emissions produced by each generating unit. This is known as Emission Dispatch (EmD). OBJECTIVES
