This is the second edition of a textbook that is intended for a senior or graduate-level
course in an electrical engineering (EE) curriculum on the subject of the analysis of
multiconductor transmission lines (MTLs). It will also serve as a useful reference
for industry professionals.
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.
In the early days, embedded systems were built primarily by engineers in a
pretty exclusive club. Embedded devices and software tools were expensive,
and building a functional prototype required significant software engineering
and electrical engineering experience.

We use the internal AD converter to real-time sampling the referenced grid voltage signal, outputting voltage of photovoltaic, feedback outputting voltage and current signal. The PWM module generates SVPWM according to the calculation of the real-time sampling data, to control the full MOSFET inverter bridge output sine wave. We realized that the output voltage of the simulator can track the frequency and phase of the referenced grid voltage with PI regulation, and the maximum photovoltaic power tracking with constant voltage regulation, thereby achieved the purpose of grid-connected simulation. Additionally, this device has the over-voltage and over-current protection, audible and visual alarm, islanding detecting and protection, and it can recover automatically. The testing shows that our design is feasible.Keywords: Photovoltaic Grid-connected，MPPT，DSP 目錄引言 11. 方案論證 11.1. 總體介紹 11.2. 光伏電池模擬裝置 11.3. DC-AC逆變橋 11.4.
