Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] like figure 1 As shown, this embodiment provides a coordinated control algorithm for emergency power supply of multiple mobile energy storage vehicles, which specifically includes the following steps:

[0036] Step S1: collect the operation data of each mobile energy storage vehicle;

[0037] Step S2: Select the dispatchable mobile energy storage vehicles in the system based on step S1;

[0038] Step S3: Judging whether there is an emergency power supply demand, if not, return to step S1 for data collection again; if yes, calculate the power S required by the load Load , load required power P Load ;

[0039] Step S4: According to the load demand in step S3 and the power and electricity that the schedulable mobile energy storage vehicle can provide, design all feasible schemes that can meet the load demand;

[0040] Step S5: Calculate the ene...

Abstract

The invention relates to a multi-mobile energy storage car emergency power-supply coordinating control algorithm. When a monitoring center receives an emergency power-supply requirement sent out by a load, the factors of current running states of schedulable mobile energy storage cars, the distance of the load, the road condition, required power and capacity and the like are comprehensively analyzed; and coordinating control is carried out on the mobile cars, so that the losses of the whole cars are reduced; over-charge and over-discharge of the energy storage cars are prevented; and the service lifetime of energy storage systems is prolonged.

Description

technical field [0001] The invention relates to the field of emergency power supply for mobile vehicles, in particular to a coordinated control algorithm for emergency power supply of multiple mobile energy storage vehicles. Background technique [0002] With the increasing dependence of modern society on electric energy, the rapid growth of electricity demand, and the higher and higher requirements for power supply quality, sudden power outages will inevitably cause damage to people's normal life order and the normal operation of society, especially For the particularly important loads in the primary load, once the power supply is interrupted, it will cause significant political influence or economic loss. As the main force of power grid emergency power supply equipment, the mobile emergency power supply vehicle has many advantages such as flexible maneuverability, mature technology, and rapid start-up. Electricity places play an increasingly significant role. [0003] At...
