Microgrid demonstration gateway for players communication and load monitoring and management
ABSTARCT :
The integration of decentralized generation units and the application of demand response programs brings changes to the power systems. Microgrids are emerging with relevant advantages for the power system operation. For this reason, several research projects are currently studding and finding methods to improve microgrids management. The development of adequate management systems, taking into account relevant retrofitting levels is of upmost importance. This paper presents and describes a gateway to be used in existing buildings in order to enable their integration in systems that are capable of managing microgrids. The gateway can monitor and control loads, generators and other equipment. For the case study the gateways will be installed in three buildings and integrated in SOICAM system able to manage microgrids. The results show the data retrieved by the gateways and sent to the central operation room.
EXISTING SYSTEM :
? The sniffer mode enables the installation of gateways in existing systems without damage their communications.
? Dash7 is a new protocol that tries to overcome some of the limitations that exists in the majority of the wireless communication protocols.
? This protocol was developed for low consumption and to be able to operate underwater and penetrate in heavy materials, such as, concrete walls and metallic objects.
? This combination is a key feature of our work. The emulation and simulation can fill the gaps that usually R&D centers encounter in their buildings, such as, the inexistence of residential loads.
DISADVANTAGE :
? The continuous communication between the players and the microgrid operator is essential to allow an effective energy management.
? The use of gateways can solve this problem. However, they should be well chosen in order to meet the requirements of the microgrid.
? The lack of energy data is one of the main problems in the research centres.
? The application of the gateways enables the acquisition of real-time data that can be used in microgrid management systems, solving the lack of data problem.
? This problem can be visible especially where is used hand-made solutions integrated with market solution.
PROPOSED SYSTEM :
• This paper proposes two tools that support the implementation of microgrid demonstrations, namely at laboratorial premises.
• This paper is based on the conference paper of, where is proposed a wireless gateway that enables the versatile implementation of microgrids.
• The proposed energy analyzer emulator provides a feasible an open source solution that emulates several load types.
• The paper presents a microgrid implementation using the proposed gateway and the proposed energy analyzer emulator.
• The proposed gateway was developed having in mind R&D centers, providing a feasible and simple option for microgrid implementation and demonstration.
ADVANTAGE :
? The main advantage of the system is the capability of execution demand response programs in the managed building.
? The implementation and study of microgrids regarding their management and efficiency is essential to overcome this situation.
? The massive integration of distributed generation and energy storage units brings significant advantages for the grid, but also increases the management complexity .
? The implementation of microgrids brings advantages for several players in the scope of smart grids.
? The main features and advantages of this protocol are the very low consumption and the capability of penetration in heavy material, such as, concrete walls and metallic objects.
