When implementing an energy management system, several scenarios are available. The first involves a basic starter system that gathers energy data from a specific area.
Often, these systems expand to acquire additional data from broader areas, evolving into systems that combine different contexts into collective information. Sometimes a comprehensive system is created, combining information sources from the whole organization.
Another option is to combine pro-energy systems with others, like Manufacturing Execution Systems (MES) used for the management of manufacturing operations. In comprehensive systems, an industrial data bus can connect not only MES and energy systems but every other system in a company, offering significant information development opportunities.
Considering the extensive possibilities of developing such systems at different stages, the worst possible option is to build a system closed to development. While it may serve its purpose initially, the inability to incorporate expert additions, such as AI algorithms, severely limits future perspectives.
Example 1: starter system
Typical steps in implementing a basic system include:
- Install
- Connect
- Utilize what you already have
The connection can be either wired or wireless, with wireless often being more advantageous for cost reduction and faster implementation.
In starter systems, two elements are defined: what is being measured and the reference parameters during measurements. Sharing this information online enables the analysis by individuals making relevant decisions.
Example 2: Extended system
Starter systems can be extended by expert additions incorporating embedded logic. These additions, based on expert knowledge, provide additional insights, references to classification tables, and notifications about anomalies or failures.
As more data is added, the system expands, offering greater capabilities. A notable example is Krakow Water SA., the city water distribution system, where data had been gathered on several levels for many years, until an idea emerged to develop an AI algorithm supporting the management of a second stage pumping station. This resulted in significant savings, increased technological security, and reduced pump wear.
Example 3: Integrated systems
While information about electricity or gas consumption is crucial, it’s not the only data required in manufacturing. There might be a need for additional data on the quantity of items, machine states, or technological parameters. This aligns closely with a Manufacturing Execution System (MES), whether in the cloud or locally, capable of delivering such data.
How to approach this task when there already is an energy management system implemented in a company? First of all, it is beneficial to leverage the existing infrastructure. As we already have been gathering data, we possess necessary connections, concentrators, data collectors, to which consecutive signals can be connected.
Secondly, if there already is a system that defines some data, maybe some of it can be utilized for the MES? Ideally, this should be implemented in a way that data streams are independent but create a comprehensive system for different recipients.
