Abstract
Load management and cogeneration models for big industrial electrical users in time of use tariffs have been proposed in several countries as a tool to reduce the electrical billing cost under their local structures. Some strategies drawn from these local solutions do not directly apply elsewhere. In this paper, a numerical procedure to optimize load and self-generation scheduling is applied for industrial electricity users under the billing structure of the Mexican supply company. This procedure implies the solution of a mixed integer linear programming problem. The optimal solution of this problem renders the appropriate scheduling of loads, considering self-generated and imported energy from the supply company to minimize the electrical billing costs. The results show that load management alone to place loads in off-peak periods is a good strategy to minimize costs. The model also showed that self-generation further increases the savings by appropriately molding the "billing demand".
