Explaining Measurement Concept Management.

Objective

After completing this lesson, you will be able to explain Measurement Concept Management.

Objects in Measurement Concept Management

In measurement concept management we differentiate between three concepts - classes, models, and instances.

Summary of the measurement concept hierarchy, where classes define the physical metering structure, models define the commercial or market structure and formulas, and instances represent a concrete installation at a specific address; further explanation is provided in the accompanying text.

A measurement concept class defines the technical and physical structure of the installation structure. A measurement concept model defines the commercial structure. A measurement concept model is always based on a measurement concept class. You can build different Measurement Concepts (MCs) models based on the same class which we will see later in the energy-feed in use case.

A measurement concept instance is a concrete representation of a MC model at a specific end-customer's address.

Standard Consumption

Physical Location Structure

Here you can see the first example - standard consumption. This means that the house owner only consumes electricity from the grid for example to use his/her household devices. Therefore, the energy is only flowing in one direction.

The energy consumed is measured with one single meter "GridM".

In the upper right you can see the so-called "network graph". Let's have a deeper look on the next figure.

Schematic illustrating a simple electricity measurement setup in which energy flows from the grid to an apartment through a unidirectional meter at the property line, with the measurement model linking the grid, a metering location recording active energy, and the consumer; further explanation is provided in the accompanying text.

Network Graph

Here you can see the network graph in the standard consumption scenario again.

The two circles are the so-called actors. In the standard consumption case there are two actors - the grid and the consumer which is the apartment. In the middle you can see the metering location with meter "GridM". The energy is flowing in only one direction; therefore, you can see one arrow pointing in one direction.

The register codes depend on the metering procedure which was selected in the class. There are two metering procedures: standard load profile or interval read.

Commercial Model

This is the commercial model which belongs to the standard consumption use case. In addition to the measurement concept class, in the measurement concept model you define market locations. In this example there is one market location for the consumption. On the right bottom you can see that we have 2 formulas defined for this market location - one formula for the metering procedure "interval reading" and one formula for the metering procedure "meter reading". Here the formula is very easy: the energy amount which is assigned to the market location is the energy we measure with meter "GridMeter".

Energy Feed-In

Physical Location Structure

Network Graph

Here you can see the network graph of our energy feed-in use case.

Commercial Model

To define a commercial model based on the energy feed-in use case, we can define two market locations. One consumption market location and one generation market location.

Commercial Settlement vs. Self-consumption

You can define several models based on the same class.

As an example, we take "energy feed in" scenario and build two different models on top of it

1. Commercial settlement: all produced energy is feed into the grid:

Now, we want to have a deeper look into the formulas. Based on our MC class for energy feed-in, there are many possibilities of MC models we can build. One MC model could be the so called "Commercial settlement". This term is used to describe that all electricity which is produced by the solar panel is fed into the grid. How can we define the formulas in this case? For the Generation Market Location, it is obvious that the energy which is produced is measured with meter "SolarM" - this is the meter within the metering location "Generator measurement". For the Consumption Market Location you could think: The energy which is consumed by the apartment is determined very easily; it is measurement by meter "GridM".

This is true but there is one thing to keep in mind: the amount meter GridM measures is only the amount we consume from the grid. What happens if we consume electricity which was produced by the solar panel? Then we have to add the excess amount SolarM-GridM_2.29.In case the house owner sticks to his agreement of "Commercial settlement" this amount SolarM-GridM_2.29 is equal to 0.

2. Self-consumption: Produced energy can be consumed and only the rest is feed into the grid:

Another commercial model which we can define based on the "energy feed-in" class is the "self-consumption" model. In this case the house owner is allowed to use produced energy by his own. Therefore, the energy amount consumed is calculated by meter GridM, direction supply (see above formula for market location "consumption"). The compensation the house owner gets is based on the amount which is fed into the grid - this amount is measurement by meter GridM, direction demand. Keep in mind that the amount, which is measured by GridM, direction supply could be smaller than the produced energy which is measured by meter "SolarM".

Difference Measurement

Physical Location Structure – Heat Pump

A 3rd example is this use case with a heat pump. In this example, the electricity which is needed by the heat pump is coming from the grid and could come from the solar panel.

Diagram of a household with solar panels and a heat pump, showing that a bidirectional grid meter plus a dedicated heat‑pump meter feed a difference‑measurement model to allocate energy among grid imports/exports, apartment consumption, and solar production; further explanation is provided in the accompanying text.

Commercial Model – Heat Pump

In this example, we define 3 market locations - 2 market locations for consumption and 1 market location for generation. The idea behind having two different consumption market locations is the following: The house owner may pay a lower kwh price for the energy consumed by the heat pump than for the energy consumed by the apartment. Therefore, we need to know how much electricity was consumed from the heat pump and how much energy was consumed from the apartment.

MCM Cloud App

How does MCM look like?

From a software component/license perspective, Measurement Concept Management is composed of two products:

Firstly, our cloud solution which is officially called "Cloud for Utilities foundation" (on the left).Here you define Measurement Concept Classes and Models.
Secondly, the MCM Backend Adapter in SAP S/4HANA which is part of the German Add-On "SAP S/4HANA Utilities Master Data Updates Option for Germany" resp. part of the product "Market Process Management for Utilities for SAP S/4HANA" for international market.

Here you see the master data belonging to a MCM instance as well as transfer and process documents.
