Abstract
Over the recent years there has been an immense growth in load consumption due to which, Load Management (LM) has become more significant. Energy providers around the world apply different load management concepts and techniques to improve the load profile. In order to reduce the stress over the load management, Demand Response Unit Commitment (DRUC), a new concept, has been implemented in this paper. The main feature of this concept is that both the energy providers and consumers must participate in order to get mutual benefits hence maximizing each of their profits. In this paper we discuss the time-based Demand Response Program since there is no penalty observed in this program. When the Demand Response was combined with Unit Commitment and compiled it was observed that a satisfactory solution resulted, which is proved to be mutually beneficial for both Generating Companies (GENCOs) and their customers. Here, we have used a Cat Swarm Optimization (CSO) technique to find the solution for the DRUC problem. The results are obtained using CSO technique for UC problem with and without DR program. This is compared with the results obtained using other conventional methods. The test system considered for the study is IEEE39 bus system.
Highlights
With the improvements in the power sector field over the decades, there has been a vast increase in load consumption due to heavy demand
Some of the growing issues associated with power system operation include limited supply of system resources that in turn forces the operators to operate their systems at their maximum capacity, resulting in regular price hikes in the electricity market [2]
The use of Demand Response Programs (DRPs) in power system operation increases the profit of customers as well as the operators
Summary
With the improvements in the power sector field over the decades, there has been a vast increase in load consumption due to heavy demand. Sometimes the load required is very high due to multiple consumers requiring power at the same time [1] Due to this issue, GENCOs are sometimes not able to meet the customer demands, making them unsatisfied or prompting them to terminate their contracts. All the aforementioned limitations motivate us to search for and explore novel ways to increase the efficiency of resource utilization in power operations. As one of these new ways, Demand Response (DR) has recently become a major concept in power system operation. The use of Demand Response Programs (DRPs) in power system operation increases the profit of customers as well as the operators. It encourages customers’ participation in the Demand Response Program (DRP) by rewarding them with incentives, if they agree to reduce their load demands during the peak hours of the day [3]
