Electrical Energy Management of Industrial Consumers to Increase Profitability with an Optimal Control Strategy - a case study

Mutual cooperation between the power distribution companies and industrial consumers is of special importance in promoting efficient load management. Due to this, the purpose of this paper is to study the effects of load management practices on consumers using an optimal control strategy. By using this strategy, the distribution company controls consumption of industrial consumers in two ways: time transfer of load and optimization of consumption. For this study, the distribution company is assumed as the controller and two industrial consumers are considered as the consumers controlled of the problem. First, using this strategy, the load management of consumers is studied static. In static load management, industrial consumers (controlled) present the amount of power consumption needed for the next day to the distribution company (controller) from the day before and determine how the power consumption changes during the day and night. In this case, the controller offers suggestions to minimize the financial loss or increase the benefit for the consumers. Then the controller determines the pattern of power consumption for two industrial consumers during 24 hours a day and obtains the optimal power consumption for each of consumers. In the following, load management is examined dynamic. In this case, unlike static load management, electricity distribution companies determine how and the pattern of power consumption for consumers during 24 hours a day. In this way, according to the electricity market price in the next half hour and also the information provided by the consumers controlled ones from their factories, the controllers get the optimal amount of power consumption for each of the industrial consumers. The controller then encourages consumers to follow this optimal consumption reference by defining incentives. In order to investigate the role of mutual cooperation between distribution companies and industrial units, two different scenarios are considered. One is complete cooperation between the controller and the consumer, and the other is non-cooperation between them. Finally, using the simulation results, the effects of load management in improving power consumption in two scenarios will be investigated in terms of consumer profitability.
