The increasing share of distributed energy resources and renewable energy in power systems results in a highly variable and less controllable energy production. Therefore, in order to ensure stability and to reduce the infrastructure and operation cost of the power grid, flexible and controllable demand is needed. The research area of demand side management is still very much in flux and several options are being presented which can all be used to manage loads in order to achieve a flexible and

These different control schemes are developed with different organization of the power sector in mind and thus can differ significantly in their architecture, their integration into the various markets, their integration into distribution network operation and several other aspects. This paper proposes a classification of load control policies for demand side management in smart buildings, based on external behavior: direct, indirect, transactional and autonomous control; internal operation: decision support system scope, control strategy, failure handling and architecture. This classification assists in providing an overview of the control schemes as well as different ways of representing a building. autonomous control indirect control transactional control direct control no communication one-way communication two-way communication local decision making central decision making If a building is represented as a collection of DERs, the price signal is passed to individual DERs present in the house. The control decision is taken locally in the DER based on the received price. The DER need to interpret the price and, depending on the implemented indirect control scheme, adapt online to the received price or use prediction and received future energy prices to schedule its own operation. The existing HAS communication in the building can be reused, but the communication protocols and DER interface needs to be implemented to be able to pass the price signal to a DER. C. Transactional control With transactional control, a building that is represented asa single DER acts as a single entity bidding in a local market. The HAS coordinates and schedules operation of the
