| dc.description.abstract | With increase in requirement of electrical energy in day to day there is an obvious increase in generation but as per the fact that India is very much reliant on thermal power plants for its electricity generation and the raw input to plant is coal which is available but it is limited in amount. The balance between generation and demand needs to be maintained at all time. So, the solution to this problem is use of renewable source of energy like solar, wind etc. There are various advantages of using renewable energy for generating electric energy some of which are: green energy, low cost of installation, etc. The incorporation of renewable energy into conventional grid is possible with distributed generation and microgrid. Microgrid is basically a small-scale power system which is designed to meet power demand for small area. Another probable solution for marinating the proper balance between demand and generation is by providing the control over number of loads connected. This control of load is possible with the idea of Demand side management (DSM). There are various advantages of microgrid like flexibility, reliability is increased. Apart from various advantages of microgrid there are few challenges also that comes with microgrid installation. Some of which are: cyber-attacks, maintain good power quality. Maintaining good power quality in power system is very important, since they become one of the main reasons for proper operation of power system. A grid operating normally should have voltage and frequency well within defined standard limits. This problem of voltage unbalance is more pronounced in islanded microgrid (stand-alone microgrid). In this work a control and mitigation scheme is used which only activates during peak loading hours and by using the use of thermostatically controlled to implement this control scheme the problem of voltage unbalance in the system can be reduced. The used model of thermostatically controlled load is different from conventional model of thermostatically controlled load model as in conventional model reactive power consumption is ignored. During the implementation of this control scheme to plan demand side management and to reduce voltage unbalance in the system, the customer’s thermal comfort is maintained. The source of standalone microgrid is PV array operating to deliver maximum power using P&O algorithm. The system under testing is designed and tested in MATLAB simulink environment. | |
