“…In [5], the coordinated allocation of battery energy storage system and soft open point incorporating demand response (DR), and conservation voltage reduction (CVR) schemes in an optimal operation. The CVR approach is suggested to be used on the electricity systems of Georgia Transmission Corporation, and Washington EMC in [6]. The number of watts and money saved are calculated by reducing the utility's peak power use.…”

This paper investigates the impacts of conservation voltage reduction (CVR) on electricity prices, the local market, and technical issues in distribution networks. An increase in electricity demand is one of the key challenges for developing sustainable societies. An increase in electric consumption puts immense pressure on electricity providers, which forces them to apply for load reduction programs during peak-demand time intervals. The CVR is one of the popular methods for load reduction, but how it would impact the pricing process and electricity market at the distribution level needs further investigation.

“…Since CVR efficiency depends on the types of devices connected, we can categorize electrical devices into four load groups as stated below [21,22]: (a) constant resistance loads without a feedback loop, which is also known as constant resistance loads that reduce the energy consumption for both the loads and the lines; (b) constant resistance loads with a feedback loop, which is also known as constant energy loads with a constant energy consumption (for timescales that are longer than the duration of the feedback loop); (c) constant power loads that increase the energy consumption, because of increasing line losses due to an increase in current draw based on a reduction in voltage; (d) constant current loads that reduce the energy consumption for the loads.…”

This paper presents a detailed study of the energy savings that can be achieved through residential appliances by implementing conservation voltage reduction (CVR). The computed energy savings are derived from the ZIP coefficients of a load model (static) under varying voltage conditions that represent the power consumed by each appliance tested. Multiple studies have shown energy savings at the substation level but not at the level of a specific residence and appliance; hence, the latter is the focus of this analysis. The appliances are determined based on the type of heating and cooling loads, and the daily duration of use for each appliance, which contributes to the total monthly consumption that is billed for a household are included in this study. Energy savings in Malaysia has been a focus of many current studies, and this study is the first attempt to achieve energy savings through the implementation of CVR. No published work has compared individual appliances that truly benefits from CVR, and this is addressed in this study. The main contribution of this study is that it provides very detailed and measured data that are used to analyze and generate energy savings for very specific residential appliances intended to meet every 1% voltage drop. The load model is developed for the common household appliances in Malaysia, and then a voltage reduction study is applied to the appliances as well as the Malaysian distribution networks. Here, we also provide insight for performing voltage reduction at an electric vehicle (EV) charging station in Malaysia. The results of this study should serve as a foundation for all practicing utilities engineers to address the issue of CVR in Malaysia. The CVR factors for residential, commercial, and industrial networks in Malaysia are also published in this paper.

Energy conservation has become crucial due to the present energy crisis in the world. To resolve such crises and reduce peak hours' electricity demand, the conservation voltage reduction (CVR) technique is frequently implemented in the power grid system. In this paper, experimental work along with simulation has been done to conserve energy by employing the CVR technique in a smart grid (SG). To verify the simulation result, an Arduino-based SG has been designed with a realtime clock (RTC) and Wi-Fi module esp8266. A program has been developed and burnt into a microcontroller integrated circuit (IC) of an Arduino board that senses day-to-day peak and/or offpeak hours of electricity consumption. The intelligent program that has been put in the system to control the switching of triode for AC (i.e., TRIAC) with an optocoupler to vary the firing angle α (0-π). At peak hours the developed system optimizes the output supplied voltage to load and it results in lesser supplied power at load. The energy consumption data is then sent to the ThingSpeak cloud for remote monitoring. Data aggregation and analytics can be done on ThingSpeak to estimate the energy consumption trend and according to the trend distribution management can notify the generation section for demand management. It has been found that the CVR technique is feasible in RTC-based SG systems which conserves 8.33 % energy by considering 2 ms as an optimized firing delay while the CVR factor = 1. The developed RTC-based SG could be useful in mitigating the present energy crisis in developing countries.
