Demand response control strategy for hierarchical distributed temperature-controlled loads in urban parks

Abstract

The invention relates to the field of smart grid technology and demand response. In order to reduce the amount of data communication, the sending and receiving of information can only be completed within the urban park and the overall control target of demand response can be predicted, and the time interval for different predictions can be corrected. Simulation analysis is carried out on the influence of the control effect. The technical solution adopted in the present invention is that the hierarchical distributed temperature control load demand response control strategy in the urban park includes the following steps: using the central control center to receive the power of the main line node of the distribution network and the output signal of renewable energy, and send it to each receiving station Control the regional control center in the urban park; each regional control center obtains the total heat pump power consumption in all urban parks through signal exchange, and obtains the targets of each zone through target allocation and compensation strategies; the regional control center collects temperature control loads in the zone Temperature and switch status information, and send control signals to users in the zone. The invention is mainly applied to the occasion of smart grid.

Description

technical field [0001] The invention relates to the field of smart grid technology and demand response. Specifically, it involves the hierarchical distributed temperature control load demand response control strategy in urban parks. Background technique [0002] The tight power supply has become one of the main contradictions in economic and social life. To ensure the balance between power supply and demand and to realize the safety, reliability, economy, cleanness and high efficiency of the power system has become an important guarantee for economic development and improvement of people's living standards. Relying on the advancement of market-oriented reforms and the adjustment of national energy policies, the coordination and exchange between the power network and the power market, and between the power network and power users are getting closer. Demand-side resource management has become an important measure to reduce power consumption, alleviate power shortage pressure,...

Problems solved by technology

On the other hand, considering the adverse effects of certain communication failures, such as packet loss, bit errors and delays, on power system load scheduling, power supply and demand optimization, etc., especially the wide application of low-cost communication technologies in distribution networks, This causes frequent occurrence of packet loss and bit errors in the communication process, which has a negative impact on the control effect of demand response

Therefore, in a non-ideal communication environment, the control effect of the centralized control strategy will be seriously affected, and sometimes even fail
