Embodiment Construction

[0021] The present invention will be further specifically described below in conjunction with the accompanying drawings and specific embodiments:

[0022] Glossary explanation: RTDS stands for Real Time Digital Simulator (Real Time Digital Simulator).

[0023] First, a real-time simulation model of the target distributed photovoltaic and cascade small hydropower combined power generation system is established according to the following steps.

[0024] The first step is determined by the actual distributed photovoltaic and cascade small hydropower complementary system topology figure 1 The number n of photovoltaic modules shown in , according to the existing mature modeling method, establish n real-time simulation models of photovoltaic modules, each real-time simulation model of photovoltaic modules includes distributed photovoltaic arrays, DC / AC converters, control The three-part model of the device.

[0025] The second step is determined by the actual distributed photovolt...

Abstract

The invention relates to a distributed photovoltaic and cascade small hydropower combined power generation real-time simulation system comprising a real-time digital simulator, an interface board, a communication board, a real-time simulation model, a level adapter board and a distributed photovoltaic and cascade small hydropower energy manager. The real-time simulation model, the interface boardand the communication board are located in the real-time digital simulator. The distributed photovoltaic and the cascade small hydropower energy manager is connected with the interface board through the level adapter board.The distributed photovoltaic and the cascade small hydropower energy manager is connected with the communication board. The capacity optimization allocation problem, system operation characteristics and system stability problem, system joint operation control and intelligent dispatching problem of the distributed photovoltaic and cascade small hydropower complementary systemcan be deeply researched.

Description

technical field [0001] The invention belongs to the technical field of real-time simulation, and relates to the real-time simulation technology of a combined power generation system of distributed photovoltaic and cascaded small hydropower. Background technique [0002] In recent years, on the one hand, as the country vigorously develops renewable energy power generation, industries such as cascade small hydropower and distributed photovoltaic power generation have developed more and more rapidly. On the other hand, the problem of "abandoning water, light, and wind" in my country's renewable energy is still very prominent. "Comprehensively promote the construction of distributed photovoltaic power generation, and promote the comprehensive development of new energy power with multi-energy complementarity and collaborative optimization" is an important measure for my country to solve the bottleneck of single renewable energy power generation. The joint power generation system...
