Abstract

The invention discloses a method and device for planning a distributed type power supply system. The planning method comprises the steps of establishing a resource layer model of the distributed type power supply system, wherein control variables of the resource layer model comprise a first vector for representing a system network topology and feeder linetype and a second vector for representing the installing positions of renewable energy generation units in the system and the configuration number, an object function of the resource layer model is min F=(DC+OC) / H, wherein DC represents hidden carbon emission, OC represents power generation carbon emission, and H represents a power consumption prediction value; establishing an operation layer model of the distributed type power supply system, control variables of the operation layer model comprise a third vector for representing renewable energy generation unit call power of the system during the running and calling electric energy from a superior power grid, wherein an objection function of the operation layer model is min f=OC / epsilon, wherein epsilon is a variation factor; adopting a predetermined algorithm to solve the resource layer model, obtaining optimal solutions of the first vector and the second vector, and adopting the optimal solutions to serve as a planning scheme for the distributed type power supply system. The method can effectively reduce carbon footprint of terminal power utilization.

Description

technical field [0001] The invention relates to power distribution optimization technology, in particular to a planning method and device for a distributed power supply system. Background technique [0002] Since the beginning of the 21st century, the shortage of fossil energy, climate change and environmental pollution have become common challenges facing the world. Therefore, improving the diversity of energy supply and reducing the dependence of end-use electricity on fossil energy, so as to minimize the carbon emissions caused by human activities, is an important issue facing the development of the electric power industry. [0003] Distributed Generation System (DGS) can realize local consumption of renewable energy such as wind and light by organically integrating various types of distributed generation (DG), power distribution network and terminal load. Therefore, it is an effective way to achieve the above goals. [0004] To establish a low-carbon DGS, the prerequis...
