Executing demand response programs will be effective when they are accompanied by the considerable cooperation of participants in addition to appropriate planning. Therefore, distribution companies always emphasize on the higher cooperation of participants in demand response programs. However, lack of proper planning may reduce electricity sale or may have negative impacts on the technical indices of the distribution network. Of the issues which have not been considered in most studies related to demand response are the rate of change in load and the impact of distribution network flexibility in reducing the negative impact of load response programs. In this paper, a model has been proposed that can determine the negative effect threshold for participantschr('39') cooperation in demand response programs by considering a wide range of distribution network features that change due to load shifting. Moreover, by considering flexibility in distribution network and introducing new indices, proper prioritization is proposed for applying reward and punishment policies or for determining the necessary technical changes in order to rate of change in load on each feeder. Based on the proposed model, maximum peak power reduction in determined in the RBTS-BUS5 test system. The results confirm the accuracy of the proposed model.

Hot water distribution for different purposes is one of the most important factors which have not been studied in solar water heater design. The main goal in the solar water heater installation is to receive the maximum solar radiation on a unit surface of the solar collector without considering the hot water distribution. In order to achieve the maximum solar absorption with higher efficiency, the optimum collector orientation can be determined by modification of basic solar calculations using consumption time interval and storage tank temperature. The effect of latitude, longitude and altitude on the optimum collector orientation is well investigated in classical solar calculations but the optimal collector performance is also dependent on several other factors concerning the hot water distribution. The main objective of the paper is the simultaneously optimization of design parameters such as collector direction and storage tank capacity by consideration of the consumption pattern. The results show increasing up to 7% in annual energy saving and 1.5% in economic saving.
