Abstract Reducing the dependence of microgrid upon the communication system and realizing the efficient control of multiple distributed generation of the microgrid are problems that need to be solved urgently. Through the research, based on multiple microgrid operation modes, the peer-to-peer control strategy in microgrid is investigated, and the peer-to-peer control strategy method of microgrid is given for a variety of complex control problems of distributed power According to the peer-to-peer control strategy method, distributed power supply adopts droop control in adjusting distributed power supply in output voltage and frequency; the droop controller has P-f and Q-U droop characteristics. This paper establishes a peer-to-peer control microgrid simulation model, adopts the droop controller designed in this paper to island mode and grid-connected mode, and investigates how the microgrid switches between the two modes. In accordance with Matlab/Simulink simulation outcomes, the research examines frequency, voltage and power changes in distributed generation in the microgrid, and verifies the validity and feasibility of microgrid peer-to-peer control strategy.

Engine Start

The hybrid vehicle is currently one of the research focuses of automotive industry. The mode of ‘engine start/stop strategy’ has become a crucial part in (hybrid) vehicle control strategy. In this paper, both home and abroad researches of the ‘engine start/stop control strategy’ were summed up. From automotive engineering perspective, several aspects were in-depth analyzed and discussed, including the engine providing control energy or power resources, substitutability of energy and the negative problems brought by starting/stopping the engine. According to economy and overall loss, the objective function of optimization of the strategy was proposed. For solving the related engineering application problems caused by using the engine start/stop strategy on hybrid vehicles, the appropriate additional solutions were given from three aspects such as adding power source, controlling and switching clutch program of power source, and coupling and connection of the engine and auxiliary energy, providing an important reference for related study.

Efficient Control

A method for synthesizing the control laws of a multi-section supercapacitor power supply of an electric drive is developed. The synthesized control law for an electric drive realizes the prescribed motion and minimizes the required capacitance of the power source. It is achieved through optimal disconnection and connection to the power line of the drive at designated times of one of the power supply sections. Reduction of the required capacitance of the power supply is achieved through a fuller discharge of some of its sections in motion conditions requiring a low level of electrical voltage and saving high voltage in other sections for the respective motion conditions. A mathematical formulation of the problem and a method of its solution is proposed. An example of the implementation of the proposed method is considered.
