This demonstration contributes to providing recommendations for future deployment on the cost reduction of demand response technologies , the role of consumer acceptance and commitment, the verification / measurement of active demand product delivery, the reliability of part of the value chain and the regulatory options needed to deploy efficiently.
This test allows validating the downstream interactions between:
the Aggregation of demand flexibility (a new deregulated function of the electricity system designed to become the key mediator between the electricity system players, both regulated and deregulated players, and consumers),
The EBox manages the appliances downstream according to signals received from the aggregation function and the user’s preferences. The main functionalities which have been field tested cover:
the HAN (Home Area Network) Communication system
the EBox (remote user interface, optimization algorithm, interactions) and the rest of the connected equipment (smart plugs, measuring device, smart washing machines, air conditioning management system)
external communication from the EBox to the aggregation function;
All the information regarding the electricity use and the measurements have been sent every day to the aggregation function’s server, where data is collected, in order to assess and analyze the consumers’ response to the AD events, as shown in the diagram below.
With this information and the information gathered through questionnaires and interviews performed before the test, consumers have been classified into four different clusters, each with a prototype load curve (see below) as an input to the field test.
This study has allowed pinpointing the reasons for consumer acceptance or rejection of the residential consumers about Active Demand and helping for future research about different points of view (technical, sociological, and also legal, concerning the definition of tariffs and contracts with the consumers) on the basis of six types of tests :
Functionality of the aggregation tool box (ATB): inputs to the ATB are the power to be increased or reduced, the time and the duration of the signal. Outputs are the signals to be sent to each cluster. This Aggregation signal deals with duration, power threshold, start time and incentives.
Functionality of the EBOX, i.e. analysis of the behavior of the EBox when the Aggregation’s signal is received, how it is interpreted by the EBox and what are the signals that the EBox sends to the smart plugs and smart devices.
Functionality of the smart devices, focusing on the communications between EBox and smart devices according to the outputs from the EBox algorithm.
Consumers’ responses analyzed from the aggregation function’s point of view: attention is paid with the behavior of consumers regarding the signals received, the day of the week and the hour and the duration of these signals, in order to reduce consumption in peak hours and increase it in off-peak hours.
according to incentives: attention is paid with the differences in consumers’ behavior when they receive a similar price &volume signal but with different incentives.
Consumers’ behaviour according to duration: similar to the above test case, the response of consumers when they receive similar price &volume signals is analyzed, but with a different signal duration.
 263 consumers in Castellón de la Plana, a Mediterranean city where Iberdrola is the main retail and distribution company with more than 100.000 points of supply, 600 secondary substations and 7 primary substations: they signed a contract and received an incentive for participating in the test.
