What is the disadvantage of being too optimistic or too pessimistic load modelling in power system?

Being too optimistic in load modeling can lead to underestimating demand, resulting in insufficient generation capacity and potential blackouts. Conversely, excessive pessimism can lead to overinvestment in infrastructure, increasing costs and making the system economically inefficient. Both extremes can disrupt the balance necessary for reliable power supply and strain resources, ultimately impacting system stability and financial viability. Striking a realistic balance is crucial for effective planning and operation in power systems.
