EMS Energy Manager System Tests and Results

EVOLUTION OF THE CONCEPT

2

• In recent years, systems have begun to be disseminated to improve the use of energy both in traction and in traditional areas of production and use of electricity.

• The CODLAG systems (COmbined Diesel-eLectric And Gas) have been used in the field of ship propulsion. These are hybrid systems for the propulsion of large ships (Queen Mary 2)

• .... and therefore, hybrid cars like the Toyota Prius. • With the introduction of renewable energies, the concept of

hybrid systems has been extended to the production and use of electricity for more conventional uses.

• The fundamental paradigms have become commonly used concepts.

MICROGRID

• In recent times, the study of activities related to the new concepts called Micro-grid and Smart

Grid have begun.

• The Micro-grids are a LOCAL GROUP OF SOURCES OF ELECTRICITY, ACCUMULATION AND USE that

normally work connected and in synchronization with the electrical network but that can be

disconnected and operate independently.

• Its goal is to increase:

• the ability to self-repair;

• resistance to attacks and greater resilience;

• improve the quality of energy;

• the increase in the efficiency of the energy system (losses in the network);

• make possible the high penetration of alternative energy sources (electric mobility);

reducing the cost of energy at the same time. 3

ENERGY PROBLEMS IN “BAD GRID O OFFGRID“ AREAS

• Loadshedding or rolling blackout, browning (spikes) causes a lot of problems with the power

supply, making it necessary to deploy and use diesel generators.

• The need for the use of diesel generators results in numerous other problems:

• The cost of gas oil and all the complex, costly, insecure and even uncertain logistics chain

for its supply;

• The cost and logistics of maintenance of the generators themselves;

• a low resilience caused by the only available source;

• the inability to manage "INTELLIGENT" electrical loads.

SIRA EMS (ENERGY MANAGER SYSTEM)

The SIRA solution for Micro-grids is called EMS.

• EMS monitors all the significant parameters of the various energy and load sources in order to optimize their use and increase their resilience.

• Typically Micro-grid consists of energy production groups: Electricity grid; Solar panels; Wind turbines; Batteries; Generators.

• Supervision and control is extended to loads to feed, to handle them as efficiently and resiliently as possible.

RMCS

6

RMCS (Remote Monitoring and Command System) is a platform that allows remote monitoring of the capabilities of the EMS system and its components.

Based on Google Earth, it gets general information about the system's efficiency.

Normally EMS takes its decisions automatically and autonomously.

If necessary, they can be sent from the Control Center to specific commands.

With a bidirectional communication link, in order to send to Telemetry to the Center and receive commands.

To this end, it is obviously necessary to ensure total security of communications.

RMCS's communication channel, while protected by traditional system solutions, features a 256-bit AES-based END-TO-END encryption.

Pre-existing configuration: batteries, tank 500L, diesel generator 27 KVA. Generator on for 24 hours a day.

• With the Sira EMS Micro-grid, diesel generator operating hours have been reduced to 2.1 hours per day (2.5 in winter and 1.5 in summer): in the situation found, the generator worked 24/7.

• Saving 91.5% in the use of the diesel generator.

Diesel Generator 27 KVA 2 x 2 Ton A/C HOW WE HAVE INTERVENED:

• realizing Energy Conservation measures to reduce BTU / hour and keep electronic systems and batteries at the required

temperature (ceiling thermal insulation, air loss reduction, etc).

• New batteries are able to operate at higher temperatures.

• Replaced 24,000 BTU conditioners with 12,000 BTU conditioners directly managed by EMS, with proprietary algorithm to

minimize the power required for performance equal.

• Refrigeration is constantly monitored and adapted to the external situation.

• Overvoltage and spikes have been eliminated. 14
