Abstract : The presence of power electronic equipment in the utility and customer side results in the extensive use of DC power in the system. A DC power system helps to reduce the unnecessary conversion stages thus helps in the reduction of losses in the system. This also helps to reduce in the transmission and distribution losses and also reduces the bulk use of conductors. So DC power system will become one of main power system network in the future. This paper analyzes a distribution system having industrial and residential loads that run in DC system. The power management algorithm helps in effective management of power between the consumers. The objective of the power management strategy is to achieve optimal operational performance providing high power quality, reliability and efficient energy dispatch. This helps in the effective allocation of power to the customers according to the priority, thus helping the stability of the system. For this, a distribution system consisting of industrial loads with and without captive/in-house generation facility along with residential consumers is considered. Simulation studies were carried out using MATLAB/Simulink platform. The proposed DC distribution system validated with a case study of implementing the same in an industrial area called KINFRA Industrial park at Thiruvananthapuram, Kerala, India.
