1 EDM Overview

1.1 Why using SAP EDM?

SAP Energy Data Management meets the needs of energy companies in the deregulated energy market. It provides functionality for metering and measuring load shapes, settling energy quantities, managing schedules, billing interval customers, and more.

SAP Energy Data Management provides a central database for storing all types of time series. It enables you to import, monitor, and validate key data. You can then carry out replacement-value procedures automatically or on demand, and manage the data entered. The application also allows you to link input and output parameters through formula calculation, regardless of the unit of measurement and dimension.

With SAP Energy Data Management, you have the functionality you need for complex billing, such as real-time pricing or time-of-use pricing. This enables you to bill time series from interval customers, for example. This billing is compatible with all contract types that refer to time series, including contracts for energy supply, grid usage, billing higher and lower volumes, and settlement processes.

Finally, SAP Energy Data Management includes a settlement workbench that allows you to settle the portion of the total distributor load that originates from suppliers. This means you can calculate the total energy use of all industrial and residential customers in one operational area, and then divide the entire consumption per supplier. You can also compare the actual and forecasted consumption, and then debit or credit the overtake and undertake amounts.

1.2 What’s the Energy Data Management?

Energy Data Management is a solution that fulfills requirements by offering interval reading, settlement of energy quantities, scheduling, and billing of interval energy consumption.

1.3 Terminology

Spot Market

Situation in which commerce is based on immediate delivery (现货市场) Cash market

A market in which goods are purchased either immediately for cash, as in a cash and carry contract, or where they are contracted for presently, with delivery occurring at the time of payment. All terms of the contract are negotiated between the buyer and seller.

Load Shape

Consumption measured by interval meters that is stored in an elementary profile. Interval Customer

Customer whose consumption is determined using an interval meter. Interval Meter

Digital interval meters, Meters are read locally via serial interface or infrared interface. 串行接口或者红外线接口来读取

MDM

(3)

ARM

Automated Reading Meter

1.4 Technological Changes

Digital Interval Meter

Measurement values are registered in intervals, such as 5/10/15/30/60 minutes, or in day values, Meters are read locally via serial interface or infrared interface.

非实时记录消耗的（电）表，大概 5/10/15/30/60 分钟，或者每天记录一次，才把能源（电/天 然气）消耗的数据记录在到它自己指示器中。普通的电表都是实时记录消耗的，空调开着，电 表就开始一直转转，如果是这种 interval meter，貌似会间隔（举例：5 分钟）的把消耗的记录 更新，而不是像传统电表。

这种电表通过串口和红外接口来读取读数。不知道对 GAS，应该也有类似的 interval meter。 Remote Meter Reading

Meters can be read remotely by Automated Meter Reading (AMR) System. 远程读表？挺好的东东，好像还需要一个数据感应装置,貌似！

Mass Data Processing

1.5 Profile

Contains values such as consumption and prices for a certain period. Within EDM, a profile is composed of header data and profile values. Data stored within a profile

 Historical data: Actual (measured) meter readings

 Forecast data: Estimated energy consumption or forecast for a customer's future usage

 Plan data: Proposed energy to be consumed by each supplier (aggregation of forecast and/or historical data)

 Conversion factor profile (such as gas law deviation factor)

 Time series, price, temperature, and so on

1.6 Complex Billing

The following 3 types of complex billing are referred to throughout this unit: Time-of-use pricing (TOU)

Real-time pricing (RTP) Spot pricing

2 EDM Relevant Data Objects

2.1 Data Objects for Deregulations

Point of delivery: The point to which a utility service is supplied, or for which a utility service can be determined. A point of delivery has an external identifier (External UI), a unique number or fixed code (Internal UI), called a point of delivery ID (will be covered in detail in this unit). Multiple services can be linked to a point of delivery.

Service provider: A company that provides a service to a point of delivery.

Profile: Time series data that contains values such as consumption or prices for a certain period.

Synthetic profile: Profile containing values generated on the basis of predefined periods (defined by day and season groups) and corresponding day and annual profiles. Synthetic profiles are used for classifying customers and customer groups (see unit: Synthetic Profiles).

2.2 Point of Delivery

A Point of Delivery is the point to which a utility service is supplied. A point of delivery is identified by mean of a unique key (PoD ID).

Table: EUITRANS created a connection between the internal POD and the external POD.

(5)

For user, its not visible in UI, user couldn’t see it in POD detail information screen; the External POD id is visible only.

Internal POD ID and External POD ID

Internal POD id is created when you save a new Installation without External POD id.

When you enter an external PDO ID for this installation, the connection between internal POD id and External ID would be created.

Check this entry in table EUITRANS, we can see the connection.

It is relevant to all process in the deregulated environment (BOR Object: ISUPOD)

2.2.1 POD Roles

2-Contracts Model

For an example, E.ON is a supplier, but also a distributor, and there is only 1 SAP ISU system.

BPContract Account->Contract A (GAS Supplier) -> Device Contract B (Grid)

(6)

2.2.2 POD Related Customizing

Configuration Path

SAP Utilities→ Master Data → Point of Delivery

2.2.3 PoD Types and Roles

Types

Standard point of delivery:

a PoD with physical representation in the energy network. Virtual point of delivery:

It represents a point of delivery that summarizes or compresses energy data (for example, for billing company codes).

Allocated at installation level.

Groups together several standard points of delivery categories.

2.2.4 PoD Service

(7)

Point of Delivery Service

 A service that is rendered by a service provider at a point of delivery.

A PoD service is a non-billable service used only for information purposes. For example, meter reading

 Note: A billable service corresponds to a contract.

 All services are allocated to a service type and a service provider.

按照目前所接触的项目，POD的作用除了用于不同的service provider之间传递信息，比如用户 的实际消耗，计划消耗等等。在LCC欧洲自由能源市场这个新环境下，PoD还被用作不同的 supplier之间做change of supplier的一个key，用PoD来表示唯一个物理设备的位置，标识一个 installation，当然这些PoD的Role肯定是Deregulation PoD。

比如还可以把Capacity values传输到需要这些信息的service provider中，比如settlement coordinator.
