The Punjab State Electricity Regulatory Commission (PSERC) has approved the procedure for forecasting, scheduling, and deviation settlement of solar and wind generation. This will come into effect from January 1, 2020. The PSERC has directed the solar and wind project developers to establish the required forecasting and communication infrastructure and register with the state load despatch centre before January, 2020.
With the large-scale integration of wind-and solar-based generating stations, managing the national and regional grids could be a daunting task for the state load despatch centres (SLDCs). Unless steps for managing variable renewable integration into the grid are initiated, issues such as poor grid management, inefficient load generation balancing, lack of grid security and instability are likely to persist across all renewable-rich states.
Effective management of renewable energy is only possible when grid operators have visibility into the amount of renewable energy expected to be injected into the grid on a day-to-day basis. To this end, the forecasting and scheduling of renewable energy is critical to anticipate the balancing requirements and procure adequate reserves for maintaining grid reliability. Special provisions also need to be in place to ensure that renewable energy generators are not unduly penalised for an unexpected loss in generation due to fluctuating weather conditions. To this end, most states have acknowledged the need to frame regulations on forecasting, scheduling and deviation settlement for grid-connected solar and wind power projects.
