Grouping control strategy for aggregated thermostatically controlled loads
Electric Power Systems Research, 2019Abstract Thermostatically controlled loads (TCLs) have great potential to participate in demand response (DR) programs due to their thermal storage and transfer characteristics. In this paper, we propose a grouping control strategy based on customer comfort and power matching degree for aggregated TCLs.

Multilayered Self-triggered Control for Thermostatically Controlled Loads
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019In this paper, a controller with multilayer structure is proposed to regulate the thermostatically controlled loads (TCLs), so that power sharing and comfort states consensus can be achieved. Since TCLs have great potential to reduce the fluctuations caused by photovoltaic in the building microgrid community, the control of a cluster of TCLs has ...

Local Communication in Populations of Thermostatically Controlled Loads
ASME Journal of Engineering for Sustainable Buildings and Cities, 2020Abstract Thermostatically controlled loads (TCLs) have shown great potential for demand response (DR) in electric grid operations. However, it has been commonly seen that DR events using TCLs may cause load synchronization and unwanted oscillatory effects, especially in homogeneous populations.

Hierarchical control of thermostatically controlled loads oriented smart buildings
Applied Energy, 2019Abstract With the transition of energy systems, synergetic interaction between consumers and suppliers has been an inevitable trend. As a demand response (DR) resource, thermostatically controlled loads (TCLs) can respond to power fluctuations in power grids caused by renewable energy and load activities by means of TCLs’ characteristics of good ...

State Estimation and Control of Heterogeneous Thermostatically Controlled Loads for Load Following
2012 45th Hawaii International Conference on System Sciences, 2012Thermostatically controlled loads (TCLs), such as refrigerators, air conditioners, and electric water heaters, can be aggregated and used to deliver power systems services. The effectiveness of control strategies depends on the level of infrastructure and communications.

Primary Frequency Control in Isolated Microgrids Using Thermostatically Controllable Loads
IEEE Transactions on Smart Grid, 2021Hybrid renewable energy sources (RES)-diesel systems are now being considered as an economic, attractive and clean option for remote isolated microgrids, to offset diesel consumption by displacing generation from conventional units; however, system security and stability is a challenge as the penetration of RES increases.

The flexibility of Thermostatically Controlled Loads for regulation
2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2016Residential Thermostatically Controlled Load (TCL) is an effective resource to participate in power grid active power balancing. However, its distributive characteristic makes control center difficult to directly get its aggregated power. This paper proposed a convenient method to estimate the aggregated power of residential TCL load, which can easily ...

A PID controller for Direct Load Control of Thermostatically Controlled Appliances
2019 IEEE 58th Conference on Decision and Control (CDC), 2019Wind and Solar farms are rapidly growing to produce electricity as sustainable resources; however, integrating these renewable resources into the existing power system has introduced new challenges due to their rapid fluctuations. These fast varying generation tends to decrease the reliability of the grid. Managing the demand side is one method to cope
