Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The calculation example in this paper adopts the extended IEEE 33 node power distribution system, such as figure 2 shown. The rated voltage of the system is 12.66kV, and the maximum total load of the network is (4427+j2547)kVA. The node voltage ranges from 0.95 to 1.05p.u., the maximum carrying capacity of the line between node 1 and node 5 is 0.474kA, and the maximum carrying capacity of other lines is 0.316kA. In this paper, it is assumed that the photovoltaic power supply and energy storage are pure active power output, and the power factors of fans, micro gas turbines and interruptible loads are all 0.95. The rated capacity of a single photovoltaic power supply and fan is 1MW; the adjustable capacity of the micro gas turbine is 600kW, and the maximum ramp rate is 180kW / h. The capacity of the energy storage device is 1MW...

Abstract

This paper discloses an active distribution network optimal dispatching method which takes into account the interests of different agents, includes the following steps: considering schedulable distributed generation, Energy storage, on-load tap changer, active control and management of packet switching capacitors and demand side resources, While considering environmental benefits, Taking into account the interests of distribution companies and distributed generation companies, an active distribution network day-ahead optimal dispatching model is established to minimize the operating cost of distribution companies, maximize the net income of distributed generation companies and minimize the emission of pollutants, and an improved bat algorithm based on diversity strategy is proposed to solve the problem. The entropy-weighted TOPSIS method is used to make comprehensive decision, and the optimal scheduling scheme is selected from the Pareto solution set.

Description

technical field [0001] The invention relates to the field of optimal scheduling of active distribution networks, and more specifically relates to an optimal scheduling method for active distribution networks that takes into account the interests of different subjects. Background technique [0002] Distributed generation (DG) in the power system can be divided into two types: dispatchable distributed generation and non-schedulable distributed generation according to its control characteristics. Schedulable DGs are generally non-intermittent and controllable power sources, such as micro-gas turbines (MT), fuel cells, etc.; the output of non-schedulable DGs depends on environmental factors, which is intermittent and uncertain. Therefore, it is uncontrollable, such as photovoltaic power supply (photovoltaic, PV), fan (wind turbine, WT) and so on. Through the control and management of controllable resources such as schedulable distributed power, ensuring the safe and economical ...
