Energy Management of the Commercial Building Using Simulation Modelling

Abstract

Due to an increase in the development of country, there has been an increase in demand of energy. This increase in energy could not be wholly met by conventional sources of energy as they are fastly depleting. At the same time power sector has gone through privatization. Also, deregulation in energy sector has brought competition in the power sector. To get rid of the problem of power crises, energy management has been taken as an alternative. It reduces the energy consumption, increases reliability and efficiency keeping in view the customer’s comfort. In this dissertation, a hybrid system consisting of photovoltaic system and wind energy conversion system is acting as renewable source. The hybrid system is connected to the utility grid. Both the energy sources are parallel linked through a DC/DC converter. The DC/AC converter converts the DC power available from PV array into three phase AC power. Simulation results shows that hybrid system provides constant power to the loads even when the power is not available from the utility grid. Excess energy, if available, could be stored in battery storage system. In this dissertation, energy management of the critical and non-critical loads of commercial building is proposed. The energy management of the commercial building is done in which there are critical loads and non-critical loads. The energy management is done by assigning priorities to the different non-critical loads in such a way that they enter into power saving mode by means of a control agent that is an intelligent control system.
