Distributed photovoltaic power generation regional integrated control method

Abstract

The invention discloses a distributed photovoltaic power generation regional integrated control method. An adopted integrated control system comprises a photovoltaic cell array, a distributed inverter control system, a sensor network, an intra-region electric control system, a regional integrated control center system and a power dispatching control center, wherein the photovoltaic cell array converts photovoltaic energy into direct current electric energy; the distributed inverter control system is used for control over the photovoltaic cell array and direct current inversion; the sensor network and the intra-region electric control system are used for monitoring and controlling each piece of electric equipment in a region and ensuring the safety of electric facilities; the regional integrated control center system manages power generation running and centralized grid connection in the region; and the power dispatching control center is used for regional status monitoring and power dispatching. By the method, low-power distributed photovoltaic power generation devices in a certain region can be connected with one another for centralized grid connection management and accept the dispatching of the power dispatching control center to realize a flexible, high-efficiency and reliable utilization form for photovoltaic power, the remote parameter measurement and control of a photovoltaic power generation system and the power dispatching.

Description

technical field [0001] The invention relates to a distributed photovoltaic power generation grid-connected system and the field of detection and control thereof, in particular to a control method for distributed photovoltaic power generation regional integrated grid-connected and a distributed power dispatching strategy. Background technique [0002] With the development of economy, energy shortage is a problem that every country in the world is facing. At the same time, as the most important available petrochemical energy materials such as coal, oil, natural gas, etc. are facing the danger of depletion, the problem of energy shortage is becoming more and more serious, and affects people's living standards. On the other hand, environmental pollution and climate warming caused by petrochemical energy can no longer be ignored, affecting the development and promotion of sustainable development, energy saving and environmental protection concepts, and are attracting more and mor...
