Abstract:With the further development of the spot electricity market, higher requirements are put forward for power supply service capability. The construction of smart grid and ubiquitous power Internet of things can effectively support interactive user service and demand response, so as to improve customer service level and flexible perception ability. In recent years, with the continuous improvement of demand side management technology, the demand side response behavior of users has made the load possible to become a relatively controllable resource, but the domestic demand side response has not been integrated with the construction of power market, which has restricted the development of demand side response to a certain extent. In view of this, the demand side response model of PJM in the United States is studied. Then a reference business model of demand response based on the current situation of Zhejiang electricity market development and national policies is proposed. On this basis, the future demand response application platform based on the Internet is envisaged.

The self-feeding device can realize remote automatic closing by relying on its built-in power mechanism or energy storage components, thus completing the closed loop operation of arrears-power off-renewal-closing. The whole process is automated, and the time of re-transmission is shortened.
