Heuristic Transmission Expansion Planning Analysis Considering Generation Uncertainty

Operational planning is an essential activity in the context of power systems for adapting generation units to system load to prevent energy deficits. Studies that aid in the optimization of generation dispatch can present global economic benefit in the operation of the system, either by reducing generation costs, enhancing reliability, reducing costs. In this view, this work presents a power system optimal operation analysis considering minimization of losses and generation costs using a heuristic approach. A system expansion is determined under normal and load growth situations considering long-term cost of losses and short-term dispatch alternatives are developed considering Marginal Operational Cost (MCO) under varying generation parameters such as water storage and affluence, to determine optimal operation point. The technical performance of the alternatives is evaluated using load flow simulation in a power system simulator environment (ANAREDE). The proposed solution method is compared with classical Optimal Power Flow (OPF) considering operational cost and total system losses. The effectiveness of the implemented solution method over the classical OPF is illustrated using the IEEE 14 bus test system.
