This work proposes the compilation of studies of different strategies of Peak Shaving Systems. These systems aim to offset part of consumer demand so as to suppress the peak of their load curve. Given that this type of system aims to prevent consumers from exceeding their Contracted Demand, suffer economic losses, need to disconnect their loads in order to save electricity and thus disrupt their production processes. In fact, a Peak Shaving System can generate revenue for the consumer when it is disconnected from the utility network, supplying their demand through another source of electricity. It also benefits the distribution system by avoiding network overloads. To elaborate this work, we analyze the strategies of Peak Shaving Systems with Diesel Generator, Peak Shaving Systems with Load Modulation and Peak Shaving Systems with Renewable Energy, being the latter strategy made by photovoltaic power generation. So, the analysis of each of these strategies is based on two scenarios: Scenario I - offsetting the electricity consumption of the consumer who is above the contracted demand line - and Scenario II - compensation electricity consumption consumer at rush hour. The consumer used in the case study based on the work is the Federal University of Maranhão, whose load curve - exceeding the Contracted Demand on all working days - demonstrates a challenge in load compensation. And the economic analysis performed of the strategies in each scenario is done through the methods of Simple Payback, Discounted Payback and Net Present Value. Thus, the paper aims to find out which methods are most viable and economically advantageous for the consumer.
