# Effect of Demand Side Management on the Operation of PV-Integrated Distribution Systems
## 1 Introduction
This method divides loads into groups of different colors based on how flexible these loads are in terms of shutting the loads off at a given time. Then, DLC was implemented while considering the aforementioned algorithm. The benefits of CVR in terms of energy savings and loss reduction have been studied [35; 36]. The authors of [37] showed that CVR provides energy and economic savings for the utility and the customer. Different implementation methods of CVR are described in [38]. In [39], the authors presented a comprehensive analysis of the possible impacts of different penetration levels of DG on voltage profiles in low-voltage secondary distribution networks. [PERSON] et al. [40] proposed to implement DSM through load curtailment of constant impedance loads on a radial network by using CVR. The method simulated intended to operate substations at rated voltage and then find the optimal capacitor position (OCP) to keep different bus voltages near their lower voltage limit (the lowest allowed voltage by energy authority regulations); this reduction in bus voltage would lead to lowering the demand; by taking the OCP, the technical losses in the network are lower. A field-validated load model for the calculation of the energy conservation gains due to CVR in secondary networks is presented in [41]. The aforementioned review shows that researchers have focused on the implementation of each DSM technique individually; in addition, some researchers have investigated the existence of DSM lacking the presence of intermittent distributed energy resources and its impact when applying DLC and CVR separately. On the other hand, many researchers have proposed appealing results and methods for DLC and CVR, but these methods have not investigated the periods of the day and the commutation between the dominance of DLC and CVR techniques to achieve the maximum reduction of consumed energy. The main contribution of this paper is to investigate the effects of implementing the algorithms of CVR and DLC on the operation of PV-integrated distribution systems. Various possible integration scenarios between PV, CVR and DLC are illustrated. The use of both CVRand DLC is suggested and tested based on two methods: the first method consists of running CVR and DLC proposed algorithm during the entire day (24-h), while the second method implements CVR during low peak demand periods and DLC during high peak demand periods. Moreover, the optimal integration of such schemes constraining the reduction of energy consumed by the user and utility is presented. This paper also shows how the integration of PV can alleviate voltage violations when CVR is applied as well as how the combination of CVR, DLC and PV allows further increasing in the energy savings. This paper is organized into four sections and the rest of the paper is prepared as follows: Section 2 gives an introduction about DSM technology, including a brief description of DSM techniques. Moreover, the CVR and DLC algorithms and implementation are addressed in this section. Section 3 presents simulation results and the verification of the proposed algorithms. In addition, in this section, different scenarios are established by the commutation between the existence of DG, CVR and DLC. The last section concludes the work presented.
