load / Demand Response: The problem of peak load demand is that it may exceed current supply capacities which will make it necessary to build expensive new generating stations to meet the peak load demand. To overcome this problem, the utility introduces demand management by encouraging the consumer to participate in the demand response methods , In these methods, incentives are offered to customers depending on their behavior in the demand response programs. Normally, customers change their consumption voluntarily. However, in some cases, the failure to meet the requirements will result in a penalty for customers. Generally, there are many types of incentive-based demand responses includes: Direct load control (DCL): According to the advanced agreement between customers and utilities, utilities can remotely control some customers’ appliances (e.g., air conditioners and water heaters). The notices for the operation are normally announced a short time ahead. To participate in this method, customers need to be equipped with a remote-control switch system so that utilities can reschedule, turn on, or turn off the appliances. Direct load control is primarily applied to the residential sector or small-scale commercial sector. It is not suitable for the industrial sector because the industrial sector needs a precise process. interruptible/curtailable load tariff: Compared with direct load control, this method is normally applied to the industrial sector and large-scale commercial sector. When the system is congested, customers are asked to reduce some loads to a certain level. By participating in this, customers can receive a rate discount or bill discount. However, if customers fail to respond in the predefined time period, they could receive a penalty. In this method, the operation frequency and the duration are limited. Emergency demand response program Instead of being asked by the utilities to take part in demand response programs, customers can make decisions by themselves in this method. On the basis of the generation and demand situation, utilities announce the total amount of electricity that must be curtailed. Customers can bid for the amount on the basis of their own situation and the wholesale market. Once the bid has been accepted, customers must provide the specified curtailment, otherwise, they will receive a penalty. This method is also suitable for largescale customers. Small-scale customers can be integrated by aggregators and involved as a unit. The regulatory framework through which electricity pricing is determined. But when the system is short of reserve, customers are required to reduce their predefined consumption. The announcement is normally released one day ahead. These curtailments are treated as system capacity to replace the conventional generation and delivery resources. By proving their ability for curtailment, customers can receive a reservation payment. And by providing the reduction, customers can receive an incentive. In contrast, if they fail to provide it, they could receive a penalty.
