Energy system and method for controlling load balancing therein

A method for controlling load balancing within an energy system, the method comprising:

• providing a renewable energy source for sharing local renewable energy consumption between a predetermined number of users who operate time delay-tolerant loads;
• providing a back-up energy source for providing back-up energy to the users in situations in which an energy demand of the users exceeds an availability or a predetermined availability level of renewable energy from the renewable energy source;
• defining use cases of appliances of the users by power profiles that are in each case based on a duration and energy consumption of at least one task or an array of subtasks, at least one of the use cases having a user specified deadline;
• performing, by a scheduler in a first level, a control of load balancing by at least one of scheduling or time-shifting use of the loads so as to provide a start time assignment for each of the tasks or subtasks based on a maximization of the local renewable energy consumption among the users;
• and
• assigning, by the scheduler in a second level, the renewable energy to the appliances of the users using the start time assignments,
• wherein the at least one of scheduling or time-shifting is performed periodically by the scheduler at an adjustable frequency.
