“…As proved by references [20][21][22][23][24][25][26][27] , active and reactive power imbalance cause frequency and voltage deviation from their ratings, respectively. Thus, active power coordination and frequency control are regarded the same control demand, and so are reactive power coordination and voltage control.…”

Micro-Grid (MG) integrates renewable generation, storage devices and controllable generations, it provides efficent utilization of clean energy while keeping stable external characteristics. Capability of continuous power supply, high scalability and flexible operation modes can satifiy the current demand of joint operation of renewable generation and Macro-Grid, and will provide a solid foundation for smart grid technology in the future. Thus, MG is an excellent integration of renewable energy utilization with a bright future, Multi-Agent System (MAS) is a new hierarchical control platform and can completely cover all the devices within a MG, its flexible control modes meet the needs of various operations of MG, and the capability of distributed computing supports intelligent functions of MG in the future. Therefore, developing premium functions for MAS in MG control will promote the development of both MG and Smart Grid technologies. This paper reviews the current applications of MAS technology for MG both in basic and advanced control demands. For basic demands concerning safe operations for MG, functions of MAS are available, but a further improvement of performance is essential for future researches to increase penetration of MAS in MG control; For advanced demands, MAS should increase calculation speed to meet the complex need of MG. In the last part, the future focuses are also depicted.

“…For the integration of a variety of distributed energy resources (DERs), MGs play an important role [3,4]. In MGs, the produced power by renewable energy sources (RESs) including photovoltaic (PV) units and wind turbine generators (WTGs) has disadvantages such as low inertia, uncertainty, and dynamic complexity [5,6].…”

Aiming at restructuring the conventional energy delivery infrastructure, the concept of energy Internet (EI) has become popular in recent years. Outstanding benefits from an EI include openness, robustness and reliability. Most of the existing literatures focus on the conceptual design of EI and are lack of theoretical investigation on developing specific control strategies for the operation of EI. In this paper, a class of control strategies for EI considering system robustness and operation cost optimization is investigated. Focusing on the EI system robustness issue, system parameter uncertainty, external disturbance and tracking error are taken into consideration, and we formulate such robust control issue as a structure specified mixed H 2 /H ∞ control problem. When formulating the operation cost optimization problem, three aspects are considered: realizing the bottom-up energy management principle, reducing the cost involved by power delivery from power grid (PG) to microgrid (MG), and avoiding the situation of over-control. We highlight that this is the very first time that the above targets are considered simultaneously in the field of EI. The integrated control issue is considered in frequency domain and is solved by a particle swarm optimization (PSO) algorithm. Simulation results show that our proposed method achieves the targets.

“…Microgrids are defined as systems that have at least one distributed energy resource (DER) and associated loads, which can perform in electrical distribution systems and provide better power quality to the end customers independently compared with the traditional utility [1]. Microgrids can also contribute in global emissions and energy losses.…”

“…Many microgrid projects focus on delivering power while other forms of energy need, such as heat, are necessary. So the combined cooling, heating and power (CCHP) are proposed [1]. A microgrid could be constructed from the most economical combination of heat and electricity.…”

“…So the combination of heat and electricity typically provide heat for industrial processes, on-site space heating, local district heating, for domestic hot water or sterilization in a hospital. There are three immediately apparent potential applications of heat and electricity in microgrids [1]: 1) Space heating, domestic hot water heating and sterilization; 2)…”

In this paper, a control scheme is proposed for a microgrid. In the proposed scheme, by controlling cooling, heating loads (C/H loads), balance between generation and consumption power is kept, and the frequency remains within its nominal value. Application of storage systems imposes costs, operating and maintenance problems to the microgrid owners. Moreover, the charge and discharge process of batteries causes reduction in their lives time. The dominant concept of this scheme is to control frequency without any storage. In this case, the coincidence of generation and consumption in C/H load technology is not necessary. This control system changes the consumption power of C/H loads and responses to unbalance power of microgrid, fast. Moreover, two indices are defined to assess the performance of the microgrid.
