Original abstract

In this research work, an energy management framework for a data centre powered by a combination of solar and grid energy is proposed. A service-level objective (SLO) is assigned to every individual zone of the data centre, which is specified by each data centre's energy requirement. Jobs with the same SLO will be assigned to the same data centre zone, and each zone will be fuelled by renewable source with a chance of generating electricity equal to or greater than the area's need. To address the intermittency issues associated with renewable energy sources and reduce SLO violations, an effective mapping strategy for renewable energy sources and data centre zones was developed using the reinforcement learning technique Deep Q-Network (DQN) algorithm to ensure maximum data centre uptime. A Particle Swarm Optimisation (PSO) algorithm is then applied to maximise the use of renewable power in meeting the data centre demand. This research aids in reducing the energy utilisation impact of data centres on the national grid, thereby avoiding a national energy deficit. Consequently, the anticipated use of renewable energy will minimise environmental degradation while boosting the country's economy. Data centres are another potential energy buyer from geo-distributed renewable energy sources in Pakistan's power market, according to our analysis.
