Abstract

The invention discloses a dynamic demand response method for a regional power grid containing new energy and temperature control load. The dynamic demand response method comprises the following steps:setting an objective function taking minimum stabilization of distributed photovoltaic power generation system output fluctuation as an objective and a constraint condition, and constructing a dynamic demand response model for the regional power grid containing a distributed photovoltaic power generation system, an electric automobile and temperature control load; resolving the dynamic demand response model for the regional power grid by adopting improved particle swarm optimization; and carrying out dynamic demand response dispatching steps for the regional power grid containing the distributed photovoltaic power generation system, the electric automobile and temperature control load. Synergic dispatching of the distributed photovoltaic power generation system, the electric automobile and temperature control load for the regional power grid can be carried out, economic dispatching management for the regional power grid can be carried out effectively, the impact of an intermittent distributed power supply and a follow-up electric automobile for the power grid is reduced, and the influence of long-time response characteristic temperature control load is stabilized.

Description

technical field

[0001] The invention belongs to the technical field of regional power grid dispatching, and in particular relates to a dynamic demand response method for a regional power grid including new energy sources and temperature-controlled loads. Background technique

[0002] Although the continuous development of renewable energy in my country has eased the tense energy situation, the intermittent, volatile and unpredictable characteristics of photovoltaic power generation system output will cause power quality to decline after distributed power generation is connected to the grid, thus affecting the stable operation of the power system. In recent years, the country has vigorously promoted the development of electric vehicles, and the scale of electric vehicles is increasing day by day. Short-term large-scale electric vehicles connected to the grid for charging will have an impact on the grid, thereby widening the peak-to-valley gap. With the development of V2G (veh...
