FAQs on Economic Load Dispatch (Solved Problem - 1) Video Lecture - GATE Notes & Videos for Electrical Engineering - Electrical Engineering (EE)

1. What is economic load dispatch?
Ans. Economic load dispatch is a method used to allocate the load demand among the available power generation units in an optimal manner. It aims to minimize the total cost of generation while meeting the load demand and satisfying the operational constraints of the power system.
2. What are the objectives of economic load dispatch?
Ans. The main objectives of economic load dispatch are to minimize the total cost of generation, maximize the efficiency of power generation units, and ensure the optimal utilization of available resources. It also aims to maintain the balance between generation and load demand and reduce the environmental impact of power generation.
3. What are the factors considered in economic load dispatch?
Ans. Several factors are considered in economic load dispatch, including the operating costs of power generation units, the fuel cost, the transmission losses, the ramp rates, and the operational constraints such as minimum and maximum generation limits of the units. The demand forecast and the availability of renewable energy sources are also taken into account.
4. How is economic load dispatch solved?
Ans. Economic load dispatch is typically solved using optimization techniques such as the gradient-based method or the evolutionary algorithms. These methods consider the objective function, which is the total cost of generation, and the constraints of the power system to determine the optimal allocation of load demand among the power generation units.
5. What are the benefits of economic load dispatch?
Ans. Economic load dispatch offers several benefits, including cost savings in power generation, improved efficiency of power plants, reduced environmental impact, and optimal utilization of resources. It also helps in maintaining the stability and reliability of the power system by balancing the generation and load demand efficiently.
