this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...

Cost-optimal planning is a very well-studied topic within planning, and it has proven to be computationally hard both in theory practice. Since cost-optimal an optimisation problem, natural analyse through the lens of approximation. An important reason for studying heuristic search; functions that guide search can often viewed as algorithms solving or approximating certain problems. Many (such ...
