  Power grids play a very important role in delivering electrical energy to
homes, industries and other places that require it. Because of this increased
demand they are facing a great challenge of voltage variations. This happens
due to varied use of energy-consuming devices and appliances like electric
vehicles, industrial consumption, occasional peak in energy demands etc. For
these fluctuations in demands, it becomes extremely important to monitor the
conditions at which the power grid operates. Once these conditions are known,
the energy production can be manipulated to meet the demand. It has been found
that the existing Power System State Estimation (PSSE) techniques may not be
good in producing optimal Performance. Moreover, they are also expensive in
terms of computational processing. To address this problem, this research
proposes a state estimation method for power grids using Convolutional Neural
Networks (CNN). It was found that the model produced an RMSE of 2.57 x 10-4,
which was comparatively accurate than one of previous studies involved in
making the estimation using a Prox Linear Model (2.97 x 10-4).
  Furthermore, the research also proposes Power System State Forecasting for
improving system awareness and resilience. The forecasting is carried out using
a model of Recurrent Neural Network (RNN). This model helps in accounting for
long-term nonlinear aspects present in data and based on that it does the
forecasting. The proposed model forecasted with a RMSE of 2.53 x 10-3, which is
comparatively equal to the previous study mentioned above (2.59 x 10-3).
