Apparatus and method for scheduling unused energy supply for plant factory based on genetic algorithm

An apparatus for scheduling an unused energy supply to a plant factory, comprising:

• a genetic data generation processor configured to generate genetic data based on sampling data including, for a preset period, a predicted energy demand per time slot for each facility of the plant factory and a predicted unused energy supply per time slot for each unused energy source;
• a population generation processor configured to generate an initial population formed of a plurality of individuals including the genetic data, and a population of a new generation including at least one of a plurality of child individuals;
• a fitness calculation processor configured to calculate a fitness for each individual based on the genetic data for each individual constituting one population and energy supply costs per time slot;
• a parent individual selection processor configured to select two or more individuals from among the plurality of individuals as parent individuals based on the fitness;
• a crossover/mutation processor configured to generate the plurality of child individuals by performing exchange and mutation of the genetic data between the parent individuals;
• and
• an energy supply scheduling processor configured to generate an optimal energy supply schedule by selecting an individual having the highest fitness from the population of each generation as an elite individual,
• wherein the genetic data generation processor is configured to generate the genetic data including unused energy storage status information per time slot (es_status[t]), an unused energy supply ratio per time slot for each facility (s_factors [i,t]), and an unused energy supply amount per time slot for each facility (supply[i,t]),
• wherein an initial value of the unused energy storage status information per time slot (es_status[t]initial) is generated as a sum of the predicted unused energy supply per time slot (supply[i,t]) and a final value of the unused energy storage status information of a previous time slot (es_status[t−1]final), and wherein the crossover/mutation processor is configured to:
• randomly exchange the unused energy supply ratio per time slot for each facility (s_factors[i,t]) between the parent individuals according to a preset crossover probability, and
• randomly change the unused energy supply ratio per time slot for each facility (s_factors[i,t]) of some of the individuals subjected to the exchange, according to a preset mutation probability.
