Several Measures for Safety and Energy Conservation of Electric Power in Residential Buildings
Wind power generation is environmentally friendly, technologically mature, highly reliable, low cost and significant scale efficiency, and is the fastest growing new energy. Many technical issues related to the grid connected operation of large wind farms need to be solved urgently. For example, the grid connected operation of large wind farms will change the distribution of the original power flow and network loss of the system, which puts forward new requirements for the planning of the power grid; It may bring power quality problems to the distribution network, such as harmonic pollution, voltage fluctuation and flicker; Adversely affect the power angle, frequency and voltage stability of the system; Wind power has strong randomness, so it is necessary to study generation and operation planning methods that can take into account the characteristics of wind power; Re evaluate the power generation reliability of the system, and analyze the capacity reliability of wind power; Research new reactive power dispatching and voltage control strategies.
