With the rapid development of electric Vehicles (EVs) as well as the promotion and
application of Vehicle-to-grid (V2G) technologies, EVs charging loads, as flexible
loads, have the potential to participate in the grid services, including peak shaving
and valley filling, frequency regulation (FR), emergency power, energy market
participation, and so on. Therefore, great attention has been paid to EVs and V2G.
Focusing on the interactions between EVs and power system, this book aims to
bring readers with basic knowledge of electrical engineering promptly to the
frontier of the EVs’ influence on power system and environment. This book may
serve as a reference for scientists, electrical engineers, and postgraduate students
majoring in electrical engineering or other related fields.

Plug in Electric Vehicles (PEVs) use energy storages usually in the form of battery
banks that are designed to be recharged using utility grid power. One category of
PEVs are Electric Vehicles (EVs) without an internal-combustion (IC) engine
where the energy stored in the battery bank is the only source of power to drive the
Vehicle. These are also referred as Battery Electric Vehicles (BEVs). The second
category of PEVs, which is more commercialized than the EVs, is the Plug in

微小型無人機(Micro／Mini UnmannedAerial Vehicle，M【，AV)在現(xiàn)代軍事和國民經(jīng)濟中發(fā)
揮著越來越重要的作用。飛行控制器是無人機系統(tǒng)的核心，它自動采集無人機的各種飛行參數(shù)，
輸出舵面／油門指令以控制無人機的姿態(tài)和軌跡，使無人機能在沒有人工操縱干預(yù)的情況下自主
飛行，完成預(yù)定的任務(wù)。因此，研制高性能的飛行控制器對改善無人機的飛行性能以及提高任
務(wù)完成效率都具有重要的意義。
本文著重研究一種通用微型飛行控制器(General Micro Flight Controller，GMFC)，以適用

2)設(shè)計了基于ARM的通用微型飛行控制器的硬件系統(tǒng)，包括主控模塊、慣性測量單元、
靜壓高度計、遙控信號接收單元、數(shù)據(jù)通信模塊、電源模塊、附加傳感器模塊等；完成了整個
