2017.04.20 Data Analytics and Optimization in Virtual Power Plant

Ask 10 Smart Energy guys what Virtual Power Plant is about, you will probably end up having 10 answers – all could be different but correct at the same time, seriously, legitimately, genuinely, correct.

To take the literal meaning of its name, VPP is just about having the power plants virtually displayed online (I am not a IT guy, I would guess there is nothing fancy about it). But that’s only the start of an entirely new evolution. What you do with the “digital copies” of the plants with all the “Big” data collected afterwards is in fact what defines virtual power plant. All kinds of the VPP derivatives, such as Asset Management, Demand Response, Micro-grid Management, Load Shedding, just to name a few, are the results coming out of this process. In here, Data Analytics and Optimization are the 2 most commonly referred to methods.

“Data Analytics” is less of a trouble to explain – anyone can bullshit in any direction and still manage to be right, it is simply too big a target to miss. Optimization, on the other hand, can be quite confusing. It is often to be either underestimated in its complexity, or mixed up with the concept of Data Analytics. Don’t get me wrong: optimization is probably part of Data Science in academic terms thus shares the same umbrella with Data Analytics. But if we are to look at it in the perspectives of business use cases and project deliverables, I would rather distinguish these 2 terminologies right from the beginning.

It is fairly challenging to do the explanation in pure text, so I took a comparison table here to help.

2017.03.21 财务工作有什么乐趣

其实我是个工程师背景读金融现做物联网的伪财务,真正“被逼”做财务工作一共不到一年,当时负责某跨国制造公司代工业务 Finance & Accounting 部门的财务报告。


道理很简单,you can’t improve something that you don’t measure. 而财务就是这个 measurement.

在有报表之前,sourcing manager 牛逼能吹上天,“代工事业为公司每月节省成本几百千欧元”,我的报表显示最多几十千,于是高层一面给 sourcing 施压,一面重新考虑把一些产能带回自家工厂。





需要声明的事,后来离职和以上的好坏都没关系。其实我还是比较喜欢讲究创造性的工作,而财务恰恰是不允许 creative accounting 的。

自诩为“美食天堂”的新加坡真的没几个好吃的地方,旧机场路 (old airport road) 的这间熟食中心算仅存的几个。

2017.02.21 the Last Mile

Just a few weeks ago I wrote a blog saying we can only hope Ma Yun to revolutionise Singapore’s e-commerce market. This weekend the news came out that a Chinese firm joined the bicycle sharing program here. The program has been stagnated for years in the sense that everybody talked about it, everybody praised it, but no one did much to make it happened.

And here you go, a Chinese firm took the leap of faith by investing 1000 bikes, a small number to Chinese Market but a long-awaited move in local perspective.
