Comprehensive Benefit Analysis of Distributed Power Grid Connection

Distributed generation can not only improve the utilization level of energy, but also bring huge economic and environmental benefits, which is conducive to the sustainable development of economy and society [1]. With the expansion of distributed generation scale and the implementation of market-oriented trading pilot, it is necessary to accurately evaluate and analyze the economic and environmental benefits of distributed generation, so it is necessary to establish an accurate evaluation model to guide grid companies and government departments to better develop and utilize distributed generation technology. As a whole, the connection between distributed generation and large power grid is helpful to save investment, reduce energy loss and give full play to their respective advantages. From the perspective of distributed generation project, it is helpful for investors to construct cost, invest reasonably and quote accurately. The benefits of distributed generation access to power grid mainly include reducing line loss, reducing power construction cost, reducing electricity price, delaying the construction of distribution and transmission cost, and improving environment and climate.
