    In my country, the electricity generation and distribution provided by
    nation grid system is not sufficient and as a result the mains voltage
    drops down to 50 V r m s in certain regions where the norminal standard
    is 220V rms.
    Relay Type Voltage Regulators are widedly used by local people to step
    up the voltage to desired level around 220.
    In my opinion, the increased in numbers of using the Voltage Regulators
    is making the whole system to become more unstable.
    And I am thinking about a better solution for the power system instead
    of using Voltage Regulators.
    Any Suggesstions?

    Yes it would.
    Those 'voltage regulators' require more current as the line voltage drops which
    in turn causes the line voltage to drop .... and so on.

    The only solution is a better grid.

    .... or to generate some of your own power. You could have a generator
    locally that makes up the difference. This way, the input impedance to
    the system can be made to remain positive and the output can be regulated.

    The alternative is some form of storage.
    If you only need say half the power for half the time, then you could
    make a circuit that charges some batteries at a known maximum load, and
    use a converter to generate the AC locally (not counting losses).
    If it was only for a PC and associated stuff, a big box of batteries and a
    modified no break supply... design a new charger... perhaps.
    All depends how long and how much power.
